Struct Handle

Source

pub struct Handle(/* private fields */);

Expand description

A capability that wraps a single Zircon handle.

Implementations§

Source §

impl Handle

Source

pub fn new(handle: NullableHandle) -> Arc<Self> ⓘ

Creates a new Handle containing a Zircon handle.

Source

pub fn duplicate(&self) -> Option<NullableHandle>

Gets a duplicate of the inner handle. Returns None if the handle has been taken or the duplicate operation fails.

Source

pub fn take(&self) -> Option<NullableHandle>

Removes the inner handle and returns it.

Source §
