Enum VecEffect 

pub enum VecEffect<'a, T> {
    Insert(usize, &'a [T]),
    Update(usize, &'a T, &'a T),
    Remove(usize, usize, &'a [T]),
}

A primitive operation that will be performed on a Vec<T> as a result of a higher level and more optimized VecMutation.

Variants

Insert(usize, &'a [T])

The given NEW items will be inserted at the given index.

Means the length of the list will INCREASE by the length of items.

Update(usize, &'a T, &'a T)

The EXISTING item at the given index will be replaced with a new value.

First sample is the previous value, second sample is the new value.

Means the length of the list will STAY THE SAME.

Remove(usize, usize, &'a [T])

The specified range of EXISTING items will be removed.

The sample at the end is the slice of items that will be removed.

Means the length of the list will DECREASE by end - start.

Trait Implementations

impl<'a, T> Clone for VecEffect<'a, T>

where T: Clone,

fn clone(&self) -> VecEffect<'a, T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T> Debug for VecEffect<'a, T>

where T: Debug,

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

Formats the value using the given formatter.

impl<'a, T> PartialEq for VecEffect<'a, T>

where T: PartialEq,

fn eq(&self, other: &VecEffect<'a, T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, T> Copy for VecEffect<'a, T>

where T: Copy,

impl<'a, T> StructuralPartialEq for VecEffect<'a, T>
