Implementations§
source§impl Value
impl Value
sourcepub fn get<I: Index>(&self, index: I) -> Option<&Value>
pub fn get<I: Index>(&self, index: I) -> Option<&Value>
Index into a YAML sequence or map. A string index can be used to access a value in a map, and a usize index can be used to access an element of an sequence.
Returns None
if the type of self
does not match the type of the
index, for example if the index is a string and self
is a sequence or
a number. Also returns None
if the given key does not exist in the map
or the given index is not within the bounds of the sequence.
use serde_yaml::Value;
let object: Value = serde_yaml::from_str(r#"{ A: 65, B: 66, C: 67 }"#)?;
let x = object.get("A").unwrap();
assert_eq!(x, 65);
let sequence: Value = serde_yaml::from_str(r#"[ "A", "B", "C" ]"#)?;
let x = sequence.get(2).unwrap();
assert_eq!(x, &Value::String("C".into()));
assert_eq!(sequence.get("A"), None);
Square brackets can also be used to index into a value in a more concise
way. This returns Value::Null
in cases where get
would have returned
None
.
let object: Value = serde_yaml::from_str(r#"
A: [a, á, à]
B: [b, b́]
C: [c, ć, ć̣, ḉ]
42: true
"#)?;
assert_eq!(object["B"][0], Value::String("b".into()));
assert_eq!(object[Value::String("D".into())], Value::Null);
assert_eq!(object["D"], Value::Null);
assert_eq!(object[0]["x"]["y"]["z"], Value::Null);
assert_eq!(object[42], Value::Bool(true));
sourcepub fn get_mut<I: Index>(&mut self, index: I) -> Option<&mut Value>
pub fn get_mut<I: Index>(&mut self, index: I) -> Option<&mut Value>
Index into a YAML sequence or map. A string index can be used to access a value in a map, and a usize index can be used to access an element of an sequence.
Returns None
if the type of self
does not match the type of the
index, for example if the index is a string and self
is a sequence or
a number. Also returns None
if the given key does not exist in the map
or the given index is not within the bounds of the sequence.
sourcepub fn is_null(&self) -> bool
pub fn is_null(&self) -> bool
Returns true if the Value
is a Null. Returns false otherwise.
For any Value on which is_null
returns true, as_null
is guaranteed
to return Some(())
.

assert_eq!(v.as_null(), None);
sourcepub fn is_bool(&self) -> bool
pub fn is_bool(&self) -> bool
Returns true if the Value
is a Boolean. Returns false otherwise.

assert!(v.is_bool());
let v: Value = serde_yaml::from_str("42").unwrap();
assert!(!v.is_bool());

If the Value
is a Boolean, returns the associated bool. Returns None
otherwise.
let v: Value = serde_yaml::from_str("true").unwrap();

sourcepub fn is_i64(&self) -> bool
pub fn is_i64(&self) -> bool
Returns true if the Value
is an integer between i64::MIN
and
i64::MAX
.
For any Value on which is_i64
returns true, as_i64
is guaranteed to
return the integer value.
let v: Value = serde_yaml::from_str("1337").unwrap();
assert!(v.is_i64());
let v: Value = serde_yaml::from_str("null").unwrap();
assert!(!v.is_i64());
sourcepub fn as_i64(&self) -> Option<i64>

sourcepub fn is_u64(&self) -> bool
pub fn is_u64(&self) -> bool
Returns true if the Value
is an integer between u64::MIN
and
u64::MAX
.
For any Value on which is_u64
returns true, as_u64
is guaranteed to
return the integer value.
let v: Value = serde_yaml::from_str("1337").unwrap();
assert!(v.is_u64());
let v: Value = serde_yaml::from_str("null").unwrap();
assert!(!v.is_u64());
sourcepub fn as_u64(&self) -> Option<u64>

sourcepub fn is_f64(&self) -> bool
pub fn is_f64(&self) -> bool
Returns true if the Value
is a number that can be represented by f64.
For any Value on which is_f64
returns true, as_f64
is guaranteed to
return the floating point value.
Currently this function returns true if and only if both is_i64
and
is_u64
return false but this is not a guarantee in the future.
let v: Value = serde_yaml::from_str("256.01").unwrap();
assert!(v.is_f64());
let v: Value = serde_yaml::from_str("true").unwrap();

assert_eq!(v.as_f64(), None);
sourcepub fn is_string(&self) -> bool
pub fn is_string(&self) -> bool

assert!(!v.is_string());

possible. Returns None otherwise.
let mut v: Value = serde_yaml::from_str("[1]").unwrap();

sourcepub fn apply_merge(&mut self) -> Result<(), Error>
pub fn apply_merge(&mut self) -> Result<(), Error>

let v: Vec<_> = vec!["lorem", "ipsum", "dolor"];

impl<I> Index<I> for Valuewhere

source§fn index(&self, index: I) -> &Value
fn index(&self, index: I) -> &Value
Index into a serde_yaml::Value
using the syntax value[0]
or
value["k"]
.
Returns Value::Null
if the type of self
does not match the type of
the index, for example if the index is a string and self
is a sequence
or a number. Also returns Value::Null
if the given key does not exist
in the map or the given index is not within the bounds of the sequence.
For retrieving deeply nested values, you should have a look at the
Value::pointer
method.
§Examples
let data: serde_yaml::Value = serde_yaml::from_str(r#"{ x: { y: [z, zz] } }"#)?;
assert_eq!(data["x"]["y"], serde_yaml::from_str::<Value>(r#"["z", "zz"]"#).unwrap());
assert_eq!(data["x"]["y"][0], serde_yaml::from_str::<Value>(r#""z""#).unwrap());
assert_eq!(data["a"], serde_yaml::from_str::<Value>(r#"null"#).unwrap()); // returns null for undefined values
assert_eq!(data["a"]["b"], serde_yaml::from_str::<Value>(r#"null"#).unwrap()); // does not panic

impl<I> IndexMut<I> for Valuewhere

source§fn index_mut(&mut self, index: I) -> &mut Value
fn index_mut(&mut self, index: I) -> &mut Value
Write into a serde_yaml::Value
using the syntax value[0] = ...
or
value["k"] = ...
.
If the index is a number, the value must be a sequence of length bigger than the index. Indexing into a value that is not a sequence or a sequence that is too small will panic.
If the index is a string, the value must be an object or null which is treated like an empty object. If the key is not already present in the object, it will be inserted with a value of null. Indexing into a value that is neither an object nor null will panic.
§Examples
let mut data: serde_yaml::Value = serde_yaml::from_str(r#"{x: 0}"#)?;
// replace an existing key
data["x"] = serde_yaml::from_str(r#"1"#)?;
// insert a new key
data["y"] = serde_yaml::from_str(r#"[false, false, false]"#)?;
// replace a value in a sequence
data["y"][0] = serde_yaml::from_str(r#"true"#)?;
// inserted a deeply nested key
data["a"]["b"]["c"]["d"] = serde_yaml::from_str(r#"true"#)?;
println!("{:?}", data);
