BoundReadMapping

Struct BoundReadMapping 

Source
pub struct BoundReadMapping { /* private fields */ }
Expand description

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§
