Trait Fingerprint 

pub trait Fingerprint {
    const TYPE_FINGERPRINT: u64;

    // Provided method
    fn fingerprint(config: Config) -> u64 { ... }
}

Available on crate feature fingerprint only.

Stable structural identity for a serializable Rust type.

Required Associated Constants

const TYPE_FINGERPRINT: u64

Hash of names, types, declaration order, and enum variant order.

Provided Methods

fn fingerprint(config: Config) -> u64

Combines the type identity with every active codec configuration field.

Dyn Compatibility

This trait is not dyn compatible.

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