Struct ChainHalt 

pub struct ChainHalt { /* private fields */ }

The verdict a writer shares with the proof of its history: once set it stays, and it carries the reason every refused write repeats.

Implementations

impl ChainHalt

pub fn awaiting_proof() -> ChainHalt

A halt that refuses every append until a verdict is set.

pub fn prove(&self)

The chain is whole. The first verdict wins.

pub fn trip(&self, reason: AxError)

Stop taking new work. The first verdict wins; a later reason is dropped, because the chain broke where the first proof said.

pub fn reason(&self) -> Option<AxError>

Why new work is refused, when the chain is broken.

pub fn proved(&self) -> bool

Whether a proof found the chain whole.

pub fn await_verdict(&self)

Blocks until there is a verdict; returns at once for a halt that admits before one.
