Struct bumpalo_herd::Member

pub struct Member<'h> { /* fields omitted */ }

A proxy for a Bump.

You get one by Herd::get.

The purpose is twofold:

• To return the inner Bump back to its Herd once this proxy is dropped.
• To allow allocation of objects with lifetime tied to the Herd.

Note

• Not all the allocation methods are exposed right now. If the others are needed, you're welcome to send a PR.
• The allocation methods are not documented here. They however correspond 1:1 to the same-named methods on Bump. See their documentation.

pub fn alloc_layout(&self, layout: Layout) -> NonNull<u8>

impl<'h> Member<'h>

pub fn as_bump(&self) -> &Bump

Access the Bump inside.

This can be used to get the Bump allocator itself, if something needs the specific type. Note that the lifetime of the Bump and the values allocated from these is tied to this Member, not to the Herd.

As this is going to be used rarely and potentially does something else then desired (eg. the shorter lifetime), this is an explicit method, not Deref.

Trait Implementations

impl<'_> Drop for Member<'_>

fn drop(&mut self)

Executes the destructor for this type.
