Struct BlockArena 

pub struct BlockArena { /* private fields */ }

Bump allocator for per-block f32 scratch buffers.

Processors borrow zeroed slices from the arena during a process call; the graph calls BlockArena::reset before each node so its capacity is reused without per-block heap allocation.

Implementations

impl BlockArena

pub fn empty() -> Self

Creates an arena with no capacity.

pub fn with_f32_capacity(capacity: usize) -> Self

Creates an arena pre-sized for capacity f32 cells.

pub fn reset(&mut self)

Releases all outstanding allocations, keeping the backing capacity.

pub fn f32_capacity(&self) -> usize

Returns the total f32 capacity of the arena.

pub fn alloc_f32(&mut self, len: usize) -> Result<&mut [f32]>

Allocates and zero-fills a len-cell f32 slice.

Fails if the request overflows or exceeds the remaining capacity.

Trait Implementations

impl Clone for BlockArena

fn clone(&self) -> BlockArena

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockArena

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

Formats the value using the given formatter.

impl Default for BlockArena

fn default() -> BlockArena

Returns the “default value” for a type.

impl PartialEq for BlockArena

fn eq(&self, other: &BlockArena) -> 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.
