Trait zk_pass::conversion::ByteConvertible

pub trait ByteConvertible<T> {
    // Required methods
    fn convert_to(t: &T) -> Vec<u8>;
    fn convert_from(bytes: &[u8]) -> Result<T, Box<dyn Error>>
       where Self: Sized;
}

A trait for converting types to and from byte representations.

This trait provides a common interface for types that can be converted to a byte array and constructed back from a byte array. It is particularly useful for cryptographic operations where serialization and deserialization of objects like points on an elliptic curve or scalars are needed.

Required Methods

fn convert_to(t: &T) -> Vec<u8>

Converts the provided object to a byte array.

Arguments

• t: A reference to the object to be converted.

Returns

A Vec<u8> representing the byte array of the object.

fn convert_from(bytes: &[u8]) -> Result<T, Box<dyn Error>>where Self: Sized,

Constructs an object from a byte array.

Arguments

• bytes: A slice of bytes from which the object should be constructed.

Returns

A Result which is Ok containing the constructed object if successful, or an Err containing an error if the conversion failed.
