Struct CommandScratch 

pub struct CommandScratch<C: Copy> { /* private fields */ }

Reusable storage for trivially owned command descriptors.

The caller clears the logical length between recording epochs. Capacity never grows, so push is allocation-free after construction.

Implementations

impl<C: Copy> CommandScratch<C>

pub fn new(capacity: usize) -> Self

Allocates storage for at most capacity commands.

pub fn clear(&mut self)

Starts a new recording epoch while retaining allocated storage.

pub fn push(&mut self, command: C) -> Result<(), ScratchFull>

Appends one command without growing storage.

Errors

Returns ScratchFull when fixed capacity is exhausted.

pub fn as_slice(&self) -> &[C]

Commands recorded in the current epoch.

pub fn as_mut_slice(&mut self) -> &mut [C]

Mutable command storage for in-place lowering or sorting.

pub const fn capacity(&self) -> usize

Fixed command capacity.

pub const fn metrics(&self) -> CommandScratchMetrics

Current cumulative counters.
