Struct DsigUbftSign 

pub struct DsigUbftSign {
    pub slices: u32,
    pub message: UbftMessage,
}

DSig signing as a uBFT service: the batch signer’s slices and certificate unit behind a request stream (crate::ubft::UbftSigner), with its own Ed25519 certificate core and the T-table rounds of the measured builds.

Fields

slices: u32

Slices (2 is the smallest buildable signer).

message: UbftMessage

Message profile and the profile-1 gate.

Trait Implementations

impl Clone for DsigUbftSign

fn clone(&self) -> DsigUbftSign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for DsigUbftSign

Available on crate feature ubft only.

fn knobs(&self) -> Vec<Knob>

The slice count, a choice of exactly the counts DSIG_SLICES builds (2, 4, 8; its value is the index into UBFT_SLICES); then the message profile and the profile-1 gate (UbftMessage).

fn name(&self) -> String

Name in the planner.

fn role(&self) -> Role

What the component does.

fn set_knob(&mut self, index: usize, value: f64)

Set knob index to value.

fn plan(&self, share: &Share, cx: &Context) -> Option<Plan>

Best build within share, or None if nothing fits.

fn build_flags(&self, _plan: &Plan) -> BuildFlags

The compile-time settings that build plan (constants, features), as key = value pairs.

fn ubft(&self) -> bool

A uBFT module: a service built to sit beside a uBFT replica (its streams and key slots), or the replica’s own footprint. Only the uBFT modes plan it, and they plan nothing else ([Mode::admits]).

fn fixed(&self) -> Option<Cost>

An allowance taken off the top of the budget before the powers divide the rest (the SHA line’s part of the LUT split), or None to take a share of its side.

fn size_for(&self, _per_second: f64, _cx: &Context) -> Option<Cost>

A line that sizes itself to demand (“auto”): the allowance of its smallest build that supplies per_second units of what it supplies (SHA-512 blocks) at cx’s clock, or None when its size is set by hand (the default). The planner ([plan_chip]) calls it with the demand of the chip it plans, so the line never limits the chip.

fn resize(&mut self, _allowance: Cost)

Remember the allowance the planner settled on for an auto-sized line ([apply_layout] calls it), so fixed and the next plan start from it.

fn unavailable(&self) -> Option<String>

Why the current knob settings cannot be planned at all (an option that is offered but not implemented yet), or None. The TUI shows it instead of “nothing fits”.

impl Debug for DsigUbftSign

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

Formats the value using the given formatter.

impl Default for DsigUbftSign

Available on crate feature ubft only.

fn default() -> Self

Two slices: the smallest build; a uBFT slot needs one signature. Profile 2.
