Function sodiumoxide::crypto::aead::chacha20poly1305::open_detached

pub fn open_detached(
    c: &mut [u8], 
    ad: Option<&[u8]>, 
    t: &Tag, 
    n: &Nonce, 
    k: &Key
) -> Result<(), ()>

open_detached() verifies and decrypts a ciphertext c toghether with optional plaintext data ad and and authentication tag tag, using a secret key k and a nonce n. c is decrypted in place, so if this function is successful it will contain the plaintext. If the ciphertext fails verification, open_detached() returns Err(()), and the ciphertext is not modified.
