RuntimeBytesMutRef

Struct RuntimeBytesMutRef 

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

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.

Source§

impl RuntimeBytesMutRef

Source

pub const fn empty() -> Self
