Struct ScratchBuffer 

pub struct ScratchBuffer<T> { /* private fields */ }

Thread-local scratch buffer for temporary allocations.

Provides a reusable buffer for algorithms that need temporary storage, avoiding repeated allocations.

Example

use u_nesting_core::memory::ScratchBuffer;

let scratch = ScratchBuffer::<f64>::new(1024);

// Use the buffer
scratch.with_buffer(|buf| {
    buf.push(1.0);
    buf.push(2.0);
    // Process data...
    buf.iter().sum::<f64>()
});
// Buffer is automatically cleared after use

Implementations

impl<T> ScratchBuffer<T>

pub fn new(capacity: usize) -> Self

Creates a new scratch buffer with the given initial capacity.

pub fn with_buffer<F, R>(&self, f: F) -> R

where F: FnOnce(&mut Vec<T>) -> R,

Executes a function with access to the buffer, clearing it afterward.

pub fn capacity(&self) -> usize

Returns the current capacity of the buffer.

pub fn shrink_if_needed(&self, max_capacity: usize)

Shrinks the buffer back to initial capacity if it has grown too large.
