Struct default_vec::DefaultVec

pub struct DefaultVec<T: Default> { /* fields omitted */ }

A vector with a default value. All uninitialized values are set to T::default().

Methods

impl<T: Default> DefaultVec<T>

fn new() -> Self

Creates an empty vector.

fn with_capacity(cap: usize) -> Self

Creates an empty vector with capacity for cap values.

fn capacity(&self) -> usize

Returns the total number of values the vector stores.

fn resize(&mut self, new_cap: usize)

Resizes the vector to contain at least new_cap values.

fn get(&self, idx: usize) -> &T

Get a reference to the value in position idx, panicking if the index is out of bounds.

fn get_mut(&mut self, idx: usize) -> &mut T

Get a reference to the value in position idx, resizing if the index is out of bounds.

fn insert(&mut self, idx: usize, val: T) -> T

Inserts a value into the vector, returning the old value.

fn remove(&mut self, idx: usize) -> T

Removes a value from the vector.

fn find<F: FnMut(&T) -> bool>(&self, start: usize, pred: F) -> usize

Starting from start, check each value in the vector and returns the index of the first one that satisfies it, or capacity() if none is found.
