Struct NrOwnedBytes 

#[repr(C)]
pub struct NrOwnedBytes {
    pub ptr: *const u8,
    pub len: u64,
    pub owner_ctx: *mut c_void,
    pub release: Option<unsafe extern "C" fn(owner_ctx: *mut c_void, ptr: *const u8, len: u64)>,
}

A callee-owned byte buffer handed across the ABI without a copy.

Contract: the consumer calls release exactly once when it is done with the bytes (possibly from a different thread than the producer), and the producer keeps ptr..ptr+len valid and immutable until then. A None release means there is nothing to free (static or arena-backed data).

Fields

ptr: *const u8

len: u64

owner_ctx: *mut c_void

release: Option<unsafe extern "C" fn(owner_ctx: *mut c_void, ptr: *const u8, len: u64)>

Implementations

impl NrOwnedBytes

pub const fn empty() -> Self

An empty payload with nothing to release.

pub const fn from_static(bytes: &'static [u8]) -> Self

Borrows static data; no release callback is needed.

pub fn from_vec(vec: Vec<u8>) -> Self

Transfers ownership of a Vec allocation; the consumer’s release call frees it in the producer’s allocator (capacity rides along in owner_ctx, so this needs no extra allocation).

Trait Implementations

impl Debug for NrOwnedBytes

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

Formats the value using the given formatter.
