Expand description

Trait that allows types to be initialized from hex strings

Required Associated Types§

source

type Error

An error occurred while parsing the hex string.

Required Methods§

source

fn from_hex_str_no_prefix<S: AsRef<str> + Into<String>>( s: S ) -> Result<Self, Self::Error>

Parses provided string as hex without requiring 0x prefix.

This is not recommended for user-supplied inputs because of possible confusion with decimals. It should be only used for existing protocols which always encode values as hex without 0x prefix.

Provided Methods§

source

fn from_hex_str<S: AsRef<str> + Into<String>>( s: S ) -> Result<Self, FromHexError<Self::Error>>

Parses provided string as hex requiring 0x prefix.

This is intended for user-supplied inputs or already-existing protocols in which 0x prefix is used.
