Expand description

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§

Source

fn new(x: usize) -> Self

Source

fn index(&self) -> usize

Source

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.
