Struct Recycler 

pub struct Recycler {
    pub num_allocations: usize,
}

Fields

num_allocations: usize

Implementations

impl Recycler

const MAX_EXTRA_CAPACITY_PERCENT: usize = 200usize

Maximum extra capacity that a recycled vector is allowed to have. If the actual capacity is larger, we re-allocate the vector storage with lower capacity.

const MIN_EXTRA_CAPACITY_PERCENT: usize = 20usize

Minimum extra capacity to keep when re-allocating the vector storage.

const MIN_VECTOR_LENGTH: usize = 16usize

Minimum sensible vector length to consider for re-allocation.

pub fn new() -> Self

pub fn recycle_vec<T>(&mut self, vec: &mut Vec<T>)

Clear a vector for re-use, while retaining the backing memory buffer. May shrink the buffer if it’s currently much larger than was actually used.

Trait Implementations

impl Debug for Recycler

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

Formats the value using the given formatter.
