Struct ra_ap_rustc_arena::DroplessArena

pub struct DroplessArena { /* private fields */ }

An arena that can hold objects of multiple different types that impl Copy and/or satisfy !mem::needs_drop.

Implementations

impl DroplessArena

pub fn alloc_raw(&self, layout: Layout) -> *mut u8

pub fn alloc<T>(&self, object: T) -> &mut T

pub fn alloc_slice<T>(&self, slice: &[T]) -> &mut [T]

where T: Copy,

Allocates a slice of objects that are copied into the DroplessArena, returning a mutable reference to it. Will panic if passed a zero-sized type.

Panics:

• Zero-sized types
• Zero-length slices

pub fn alloc_str(&self, string: &str) -> &str

Allocates a string slice that is copied into the DroplessArena, returning a reference to it. Will panic if passed an empty string.

Panics:

• Zero-length string

pub fn alloc_from_iter<T, I: IntoIterator<Item = T>>(&self, iter: I) -> &mut [T]
