Trait aws_lc_rs::aead::NonceSequence

source · 
pub trait NonceSequence {
    // Required method
    fn advance(&mut self) -> Result<Nonce, Unspecified>;
}
Expand description

A sequences of unique nonces.

A given NonceSequence must never return the same Nonce twice from advance().

A simple counter is a reasonable (but probably not ideal) NonceSequence.

Intentionally not Clone or Copy since cloning would allow duplication of the sequence.

Required Methods§

source

fn advance(&mut self) -> Result<Nonce, Unspecified>

Returns the next nonce in the sequence.

§Errors

error::Unspecified if “too many” nonces have been requested, where how many is too many is up to the implementation of NonceSequence. An implementation may that enforce a maximum number of records are sent/received under a key this way. Once advance() fails, it must fail for all subsequent calls.
