}Expand description
A unit containing a value (ex: an integer), a prefix (ex: an enum), and allowed constant suffix strings.
Required Associated Types§
Required Methods§
fn suffixes() -> &'static [&'static str]
Sourcefn convert(&self, prefix: Self::T) -> Result<Self, String>where
Self: Sized,
fn convert(&self, prefix: Self::T) -> Result<Self, String>where
Self: Sized,
Convert value to a different prefix, but return an error if the conversion cannot be done without possibly losing precision.
Sourcefn convert_lossy(&self, prefix: Self::T) -> Selfwhere
Self: Sized,
fn convert_lossy(&self, prefix: Self::T) -> Selfwhere
Self: Sized,
Convert value to a different prefix, even if it loses precision.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
