Struct linux_api::signal::siginfo_t

pub struct siginfo_t(/* private fields */);

Wrapper around linux_siginfo_t.

Invariants

The following invariants in the internal linux_siginfo_t are ensured when constructed through safe constructors:

• lsi_code, lsi_signo, and lsi_errno are initialized.
• The parts of the l_sifields union are initialized that sigaction(2) specifies are initialized for the given lsi_code and lsi_signo.

When constructing via one of the unsafe constructors that takes some form of linux_siginfo_t or the pieces of one, the above must also hold. However, it is sufficient for all bytes to be initialized; any bit pattern is acceptable as long as it is an initialized one. (Initializing from garbage data may result in garbage pointers, but the safe methods of this type will never dereference those itself). For example, unsafe { SigInfo::wrap_assume_initd(core::mem::zeroed()) } is sound.

Implementations

impl siginfo_t

pub unsafe fn wrap_assume_initd(si: linux_siginfo_t) -> Self

Analogous to bytemuck::TransparentWrapper::wrap, but unsafe.

Safety

See siginfo_t Invariants.

pub unsafe fn wrap_ref_assume_initd(si: &linux_siginfo_t) -> &Self

Analogous to bytemuck::TransparentWrapper::wrap_ref, but unsafe.

Safety

See siginfo_t Invariants.

pub unsafe fn wrap_mut_assume_initd(si: &mut linux_siginfo_t) -> &mut Self

Analogous to bytemuck::TransparentWrapper::wrap_mut, but unsafe.

Safety

See siginfo_t Invariants.

pub unsafe fn peel(si: Self) -> linux_siginfo_t

Safety

Pointers are safe to dereference iff those used to construct si are.

pub fn signal(&self) -> Result<Signal, SignalFromI32Error>

pub fn code(&self) -> Result<SigInfoCode, SigInfoCodeFromRawError>

pub unsafe fn details(&self) -> Option<SigInfoDetails>

Safety

Pointers are safe to dereference iff those used to construct self (or set via mutable methods) are.
