Enum Mode 

pub enum Mode {
    Ed25519,
    Dsig,
    UbftEd25519,
    UbftDsig,
}

Which paper the chip is planned for.

Variants

Ed25519

Ed25519 alone.

Dsig

DSig with the Ed25519 signing and verification it needs.

UbftEd25519

Ed25519 as a service beside a uBFT replica: the uBFT modules only (Component::ubft), headline idle latency rather than rate.

UbftDsig

DSig (with its Ed25519 work) as a service beside a uBFT replica.

Implementations

impl Mode

What each paper’s chip contains and needs.

pub const ALL: [Mode; 4]

Every mode, in the order the TUI offers them.

pub fn name(self) -> &'static str

Display name.

pub fn short(self) -> &'static str

Short name for the headline.

pub fn paper(self) -> Mode

The paper whose needs and splits this mode follows: a uBFT mode signs and verifies like the paper of its scheme.

pub fn is_ubft(self) -> bool

A uBFT mode: only uBFT modules take part.

pub fn op(self, side: Side) -> &'static str

What one delivered operation of the side is called.

pub fn need(self, role: Role, cx: &Context, batch: f64) -> f64

Operations of role needed per delivered operation of its side (0: the role takes no part). batch is DSig’s batch size K.

• Ed25519 paper: one Ed25519 signature per signature, one Ed25519 verification per verification.
• DSig paper: one DSig signature and 1/K Ed25519 signature per signature; one DSig verification and 1 − h Ed25519 verification per verification, h = (b/100)·(K − 1)/K (Context::cache_hit).
• A uBFT mode: as its paper; one uBFT certificate share is one signature, checking a peer’s share one verification.

pub fn uses(self, role: Role) -> bool

Whether components of role belong in this mode’s chip.

pub fn admits(self, c: &dyn Component) -> bool

Whether c belongs in this mode’s chip: its role is used and it is a uBFT module exactly when this is a uBFT mode. So the papers never plan a uBFT service, and a uBFT chip holds only the replica and its services (each with its own SHA-512, no shared line).

Trait Implementations

impl Clone for Mode

fn clone(&self) -> Mode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mode

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

Formats the value using the given formatter.

impl PartialEq for Mode

fn eq(&self, other: &Mode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Mode

impl Eq for Mode

impl StructuralPartialEq for Mode
