Struct bones_framework::prelude::bones_schema::alloc::ResizableAlloc
source · pub struct ResizableAlloc { /* private fields */ }
Expand description
A low-level memory allocation utility for creating a resizable buffer of elements of a specific layout.
The allocation has a capacity measured in the number of elements with the given Layout
that
it has room for.
Dropping a ResizableAlloc
will de-allocate it’s memory.
Implementations§
source§impl ResizableAlloc
impl ResizableAlloc
sourcepub fn new(layout: Layout) -> 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.
sourcepub fn with_capacity(
layout: Layout,
capacity: usize,
) -> Result<ResizableAlloc, LayoutError>
pub fn with_capacity( layout: Layout, capacity: usize, ) -> Result<ResizableAlloc, LayoutError>
Create a new ResizableAlloc
with the given capacity.
sourcepub fn resize(&mut self, new_capacity: usize) -> Result<(), LayoutError>
pub fn resize(&mut self, new_capacity: usize) -> Result<(), LayoutError>
Resize the buffer, re-allocating it’s memory.
sourcepub fn iter(&self) -> ResizableAllocIter<'_> ⓘ
pub fn iter(&self) -> ResizableAllocIter<'_> ⓘ
Iterate over the allocation.
sourcepub fn iter_mut(&mut self) -> ResizableAllocIterMut<'_> ⓘ
pub fn iter_mut(&mut self) -> ResizableAllocIterMut<'_> ⓘ
Iterate mutably over the allocation.
