Associated Types

type Hash: TripcodeHash

The type of hash value that represents resulting tripcodes.

See the documentation for tripcode::hash module for the information of the hash value.

Required Methods

fn try_hash<P: AsRef<[u8]>>(password: P) -> Option<Self::Hash>

Attempts to generate a hash value from password.

Returns None when passed an invalid password.

Provided Methods

fn try_generate<P: AsRef<[u8]>>(password: P) -> Option<String>

Attempts to generate a tripcode from password.

Returns None when passed an invalid password.

fn try_append<P: AsRef<[u8]>>(password: P, dst: &mut String) -> Option<()>

Attempts to generate a tripcode and append it to a String.

Returns None when passed an invalid password.

fn try_write<P, W>(password: P, dst: &mut W) -> Option<Result<()>> where
    P: AsRef<[u8]>,
    W: Write,
