Struct Ed25519Sign 

pub struct Ed25519Sign {
    pub specialized: bool,
    pub shared_sha: bool,
    pub shape: ShapeKnobs,
}

The Ed25519 signing module as a chip-planner component. Its plan is the best frontier::plan_sign_with build for the share it is given.

Fields

specialized: bool

Specialized memory layout instead of the as-built one.

shared_sha: bool

Hash through the shared SHA-512 line.

shape: ShapeKnobs

Block ratio and batch compression.

Trait Implementations

impl Clone for Ed25519Sign

fn clone(&self) -> Ed25519Sign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for Ed25519Sign

Chip-planner interface of the signing module.

fn name(&self) -> String

Display name in the TUI.

fn role(&self) -> Role

Planner role, used to report delivered signatures.

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

The two choice knobs; the selected index is 0 for the first label.

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

Applies a knob change; value is the chosen label index, and index 0 is the specialized layout or the shared line. Indices 2.. are the shape knobs (ShapeKnobs).

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

Best signing build within share at the context’s clock, or None when nothing fits. On the shared line the plan demands three SHA-512 blocks per signature from the line.

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

Compile-time settings that would build this plan: the fb,sha,sc,cp profile build.rs parses (sha = 0 on the shared line; 1,1,1,0 selects the small signer) and the SHA mode.

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”.

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]).

impl Debug for Ed25519Sign

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

Formats the value using the given formatter.

impl Default for Ed25519Sign

Defaults to the specialized layout on the shared SHA-512 line, the planner choosing the mix (manual weights start at 15:11:3, the routed 15/11/3/1).

fn default() -> Self

Returns the “default value” for a type.
