Struct UbftReplica 

pub struct UbftReplica {
    pub nodes: u32,
    pub window: u32,
}

The uBFT replica the services sit beside: a fixed allowance off the budget, sized by UBFT_DESIGN_LUT and UBFT_DESIGN_DSP (an upper bound: the shell is included). Plans as itself, with no rate.

Fields

nodes: u32

Hardware capacity; runtime membership must still be odd.

window: u32

Compile-time protocol window.

Implementations

impl UbftReplica

pub fn cost() -> Cost

Its footprint.

Trait Implementations

impl Clone for UbftReplica

fn clone(&self) -> UbftReplica

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for UbftReplica

fn name(&self) -> String

Name in the planner.

fn role(&self) -> Role

What the component does.

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

Build options.

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

Set knob index to value.

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

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

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

Best build within share, or None if nothing fits.

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

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

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: Share)

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 UbftReplica

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

Formats the value using the given formatter.

impl Default for UbftReplica

fn default() -> Self

Returns the “default value” for a type.
