Struct HasherParams 

pub struct HasherParams {
    pub message_len: Option<usize>,
    pub max_message_len: Option<usize>,
}

Circuit-shape parameters shared by every hasher example.

These are compile-time Params: they select which gadget the circuit is built from, independently of the message that is later hashed.

• --message-len builds the fixed-length gadget for exactly that many bytes.
• --max-message-len builds the variable-length gadget with that capacity.
• The two are mutually exclusive; if neither is given, the fixed-length gadget is built with DEFAULT_HASH_MESSAGE_BYTES.

Fields

message_len: Option<usize>

Fixed message length in bytes; builds the more efficient fixed-length gadget. Mutually exclusive with --max-message-len.

max_message_len: Option<usize>

Maximum message length in bytes; builds the variable-length gadget with this capacity. Mutually exclusive with --message-len.

Trait Implementations

impl Args for HasherParams

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]

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

Append to [Command] so it can instantiate self via [FromArgMatches::update_from_arg_matches_mut]

impl Clone for HasherParams

fn clone(&self) -> HasherParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HasherParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromArgMatches for HasherParams

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>
