immutable-seq-rust is a library providing an immutable sequence data structure for the Rust programming language.
The Seq implements an API similar to Vec, with the added advantage that previous versions of the data structure remain available and unchanged.
Add the dependency immutable-seq to your Cargo.toml
toml
[dependencies]
immutable-seq = "0.1.0"
Include the crate immutable-seq in your code
```rust
extern crate immutable_seq;
use immutableseq::Seq;
``
*(#[macrouse]is only required to enable theseq!` macro, shown below.)*
Create a sequence with some values
rust
let seq1: Seq<i32> = seq![1, 2, 3];
Add an element to the beginninng. Note: this creates a new sequence, with the element added, but does not change the original sequence.
rust
let seq2 = seq1.push_front(0);
assert_eq!(seq1, seq![1, 2, 3]);
assert_eq!(seq2, seq![0, 1, 2, 3]);
