Trait ToByteArray

pub trait ToByteArray {
    const NUM_FIELDS: usize;
    const IS_PRIMITIVE: bool = false;

    // Required method
    fn to_byte_array(&self) -> Result<[u8; 32], HasherError>;
}

Required Associated Constants

const NUM_FIELDS: usize

Provided Associated Constants

const IS_PRIMITIVE: bool = false

Required Methods

fn to_byte_array(&self) -> Result<[u8; 32], HasherError>

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.
