Trait IndexType

pub unsafe trait IndexType:
    Copy
    + Default
    + Hash
    + Ord
    + Debug
    + 'static {
    // Required methods
    fn new(x: usize) -> Self;
    fn index(&self) -> usize;
    fn max() -> Self;
}

Trait for the unsigned integer type used for node and edge indices.

Safety

Marked unsafe because: the trait must faithfully preserve and convert index values.

Required Methods

fn new(x: usize) -> Self

fn index(&self) -> usize

fn max() -> 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.
