resize slice (2)
Enlarge and shrink slices (given a larger slice) in safe Rust.
This is done by expressing the new slice as a slice of the source slice -- this way you can also extend the lifetime to the sources lifetime.
Example
use resize_slice2::ResizeSlice;
let source = &["a", "b", "c", "d", "e", "f"];
let slice = &source[1..4];
assert_eq!(slice, &["b", "c", "d"]);
let resized = slice.try_resize(source, 0..1).unwrap();
assert_eq!(resized, &["b", "c", "d", "e"]);
So a range of 1..-1
would move the start one to the right and move the end one to the left.
source: |------------------------|
slice: |-------|
result: |---|
A range of 1..
would move the start one to the right and fully expand the end.
source: |------------------------|
slice: |-------|
result: |-----------|
A range of 0..0
would return the same slice.
source: |------------------------|
slice: |-------|
result: |-------|
