Struct disk::qcow::vec_cache::VecCache

pub struct VecCache<T: 'static + Copy + Default> {
    vec: Box<[T]>,
    dirty: bool,
}

Represents a vector that implements the Cacheable trait so it can be held in a cache.

Fields

vec: Box<[T]>

dirty: bool

Implementations

impl<T: 'static + Copy + Default> VecCache<T>

pub fn new(count: usize) -> VecCache<T>

Creates a VecCache that can hold count elements.

pub fn from_vec(vec: Vec<T>) -> VecCache<T>

Creates a VecCache from the passed in vec.

pub fn get<I>(&self, index: I) -> Option<&<I as SliceIndex<[T]>>::Output>

where I: SliceIndex<[T]>,

pub fn get_values(&self) -> &[T]

Gets a reference to the underlying vector.

pub fn mark_clean(&mut self)

Mark this cache element as clean.

pub fn len(&self) -> usize

Returns the number of elements in the vector.
