Struct RegionHandle 

pub struct RegionHandle<'a> {
    pub id: RegionId,
    pub phantom: PhantomData<&'a ()>,
}

A lifetime-tied handle to a specific region.

The 'a lifetime ensures the handle cannot outlive the allocator that owns the underlying Region.

Fields

id: RegionId

The region this handle refers to.

phantom: PhantomData<&'a ()>

Ties the handle lifetime to the allocator borrow.

Implementations

impl<'a> RegionHandle<'a>

pub fn new(id: RegionId) -> Self

Create a handle for the given region id with an explicit lifetime.

pub fn region_id(self) -> RegionId

Expose the underlying region id.

Trait Implementations

impl<'a> Clone for RegionHandle<'a>

fn clone(&self) -> RegionHandle<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for RegionHandle<'a>

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

Formats the value using the given formatter.

impl<'a> Display for RegionHandle<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for RegionHandle<'a>

fn eq(&self, other: &RegionHandle<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
