Trait SaltGenerator 

pub trait SaltGenerator {
    // Required method
    fn next_salt(&mut self) -> Result<[u8; 16], Error>;
}

Source of 128-bit salts for issuance helpers.

The crate does not generate randomness. Issuers pass an implementation that returns one fresh, unpredictable 16-byte salt for each redacted claim, redacted array element, or decoy.

Required Methods

fn next_salt(&mut self) -> Result<[u8; 16], Error>

Returns the next 16-byte salt.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
