Struct RuntimeBytesMutRef 

#[repr(C)]
pub struct RuntimeBytesMutRef {
    pub ptr: *mut u8,
    pub len: usize,
}

Borrowed mutable byte slice passed across the C ABI.

This is a uniquely borrowed view into memory owned by the caller. The callee may mutate the bytes only during the ABI call or visitor callback and must not retain the pointer after it returns.

Fields

ptr: *mut u8

Pointer to the first byte, or null when len == 0.

len: usize

Number of bytes available at ptr.

Implementations

impl RuntimeBytesMutRef

pub const fn empty() -> Self

Returns an empty mutable byte reference.

pub fn from_slice(bytes: &mut [u8]) -> Self

Creates a mutable byte reference from a Rust slice.

Trait Implementations

impl Clone for RuntimeBytesMutRef

fn clone(&self) -> RuntimeBytesMutRef

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RuntimeBytesMutRef

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RuntimeBytesMutRef

fn eq(&self, other: &RuntimeBytesMutRef) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
