Struct HasherInstance 

pub struct HasherInstance {
    pub random_message: bool,
    pub random_message_len: Option<usize>,
    pub message: Option<String>,
}

Instance (witness) parameters shared by every hasher example.

These are proof-time Instance arguments: they choose the concrete message that is hashed by a circuit whose shape is already fixed by HasherParams.

• --message <STR> hashes a UTF-8 string.
• --random-message hashes reproducible random bytes; --random-message-len <LEN> sets the length (defaulting to the circuit’s message length / maximum). It requires --random-message.
• --message and --random-message are mutually exclusive; random is the default when neither is given.

Fields

random_message: bool

Hash reproducible random bytes. This is the default when --message is not given.

random_message_len: Option<usize>

Length in bytes of the random message. Requires --random-message; defaults to the circuit’s fixed length (or maximum, for a variable-length circuit).

message: Option<String>

Hash this UTF-8 string. Mutually exclusive with --random-message.

Trait Implementations

impl Args for HasherInstance

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::ArgGroup::id] for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate Self via [FromArgMatches::from_arg_matches_mut]
