Function rust_sodium::crypto::box_::curve25519xsalsa20poly1305::open_precomputed

pub fn open_precomputed(
    c: &[u8], 
    Nonce: &Nonce, 
    PrecomputedKey: &PrecomputedKey
) -> Result<Vec<u8>, ()>

open_precomputed() verifies and decrypts a ciphertext c using a precomputed key k and a nonce n. It returns a plaintext Ok(m). If the ciphertext fails verification, open_precomputed() returns Err(()).
