Struct BoundReadMapping 

pub struct BoundReadMapping { /* private fields */ }

Read-only witness that owns its consumed active mapping.

A region bound over this witness is a unique capability; neither the witness nor the region it backs can be duplicated:

use native_ipc::binding::BoundReadMapping;
use native_ipc::core::mapping::ReaderRegion;
fn duplicate(
    region: ReaderRegion<BoundReadMapping>,
) -> (ReaderRegion<BoundReadMapping>, ReaderRegion<BoundReadMapping>) {
    let copy = region.clone();
    (region, copy)
}

Implementations

impl BoundReadMapping

pub fn into_active(self) -> ActiveReader

Releases the witness and returns the owned active mapping unchanged.

Trait Implementations

fn base(&self) -> NonNull<u8>

Mapping base with allocation provenance.

fn len(&self) -> usize

Exact native capability size.

fn is_empty(&self) -> bool

Returns whether the capability is empty (valid witnesses are not).
