Similar is a dependency free crate for Rust that implements different diffing
algorithms and high level interfaces for it. It is based on the
inherits some ideas from there. It also incorporates the Myer's diff
algorithm which was largely written by Brandon Williams. This library was
```rust
use similar::{ChangeTag, TextDiff};
fn main() {
let diff = TextDiff::from_lines(
"Hello World\nThis is the second line.\nThis is the third.",
"Hallo Welt\nThis is the second line.\nThis is life.\nMoar and more",
);
for change in diff.iter_all_changes() {
let sign = match change.tag() {
ChangeTag::Delete => "-",
ChangeTag::Insert => "+",
ChangeTag::Equal => " ",
};
print!("{}{}", sign, change);
}
}
```
