An extension trait for std::vec::Vec.

Methods with the suffix ed are like the original methods, but consumes the vector. This is interesting to chain methods call. For example:

use fera_ext::VecExt;

assert_eq!(vec![1, 2, 3], vec![4, 3, 1, 3, 4, 2].sorted().deduped().truncated(3));

Required Methods

unsafe fn new_uninitialized(len: usize) -> Self

Creates a new vector with len uninitialized elements.

Safety

This is unsafe because some values may not be dropped or some values may be dropped without being initialized. See std::mem::uninitialized for more informations.

fn appended(self, other: &mut Self) -> Self

fn deduped(self) -> Self

where T: PartialEq,

fn deduped_by<F>(self, same_bucket: F) -> Self

where F: FnMut(&mut T, &mut T) -> bool,

fn deduped_by_key<F, K>(self, key: F) -> Self

where F: FnMut(&mut T) -> K, K: PartialEq<K>,

fn resized(self, new_len: usize, value: T) -> Self

where T: Clone,

fn reversed(self) -> Self

fn shrinked_to_fit(self) -> Self

fn shuffled(self) -> Self

Shuffle this vector using SmallRng::from_entropy().

fn shuffled_with<R: Rng>(self, rng: R) -> Self

Shuffle this vector using rng.

fn sorted(self) -> Self

where T: Ord,

fn sorted_by<F>(self, compare: F) -> Self

where F: FnMut(&T, &T) -> Ordering,

fn sorted_by_key<F, K>(self, key: F) -> Self

where F: FnMut(&T) -> K, K: Ord,

fn truncated(self, len: usize) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
