Struct bones_framework :: lib :: prelude :: bones_schema :: alloc :: ResizableAlloc Copy item path

impl ResizableAlloc

pub fn new(layout: Layout) -> ResizableAlloc

Create a new ResizableAlloc for the given memory layout. Does not actually allocate anything yet.hing.

If the new capacity is greater, it will reallocate and extend the allocated region to be able to fit new_capacity items of the this ResizableAlloc’s layout.

If the new capacity is lower, it will reallocate and remove all items

The capacity will be 0 and the pointer will be dangling.

§Panics

Panics if the provided layout is not already padded to it’s alignment.

pub fn with_capacity( layout: Layout, capacity: usize, ) -> Result<ResizableAlloc, LayoutError>

Create a new ResizableAlloc with the given capacity.

pub fn resize(&mut self, new_capacity: usize) -> Result<(), LayoutError>

Resize the buffer, re-allocating it’s memory.

pub fn layout(&self) -> Layout

Get the layout.

pub fn capacity(&self) -> usize

Get the capacity.

pub fn as_ptr(&self) -> *mut c_void

Get a raw pointer to the allocation.

pub fn iter(&self) -> ResizableAllocIter<'_> ⓘ

Iterate over the allocation.

pub fn iter_mut(&mut self) -> ResizableAllocIterMut<'_> ⓘ

Iterate mutably over the allocation.

pub unsafe fn unchecked_idx(&self, idx: usize) -> *mut c_void

Get a pointer to the item with the given index without performing any bounds checks.

§Safety

This does no checks that the index is within bounds or that the returne dpointer is unaliased.
