Trait unsafe_io::AsUnsafeHandle [−][src]
pub unsafe trait AsUnsafeHandle {
fn as_unsafe_handle(&self) -> UnsafeHandle;
fn eq_handle<Handlelike: AsUnsafeHandle>(&self, other: &Handlelike) -> bool { ... }
}Expand description
A trait for types which contain an unsafe handle and can expose it.
A type implementing AsUnsafeHandle guarantees that the return value from
as_unsafe_handle on an instance of the type is a copy of a handle which
is owned.
Safety
This trait is unsafe because types implementing it must guarantee they
own their handle.
Required methods
fn as_unsafe_handle(&self) -> UnsafeHandle
fn as_unsafe_handle(&self) -> UnsafeHandle
Return the contained unsafe handle.
Provided methods
fn eq_handle<Handlelike: AsUnsafeHandle>(&self, other: &Handlelike) -> bool
fn eq_handle<Handlelike: AsUnsafeHandle>(&self, other: &Handlelike) -> bool
Test whether self.as_unsafe_handle() is equal to
other.as_unsafe_handle().
That this depends on the guarantee that types that implement
AsUnsafeHandle own their resources, so we won’t erroneously compare
dangling handles.
