Trait BuildIndex 

pub trait BuildIndex:
    BuildIndex
    + Copy
    + Eq
    + Ord
    + Debug
    + Hash {
    // Required methods
    fn to_usize(self) -> Option<usize>;
    fn from_usize(value: usize) -> Option<Self>;
}

Unsigned dense ID width usable by graph and hypergraph builders.

Performance

Implementations perform checked conversions in O(1).

Required Methods

fn to_usize(self) -> Option<usize>

Converts this ID to usize when representable on the current target.

Performance

This function is O(1).

fn from_usize(value: usize) -> Option<Self>

Converts a usize into this ID width when representable.

Performance

This function is O(1).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
