Struct TrustThresholdFraction

Source
pub struct TrustThresholdFraction { /* private fields */ }
Expand description

TrustThresholdFraction defines what fraction of the total voting power of a known and trusted validator set is sufficient for a commit to be accepted going forward. The Default::default() returns true, iff at least a third of the trusted voting power signed (in other words at least one honest validator signed). Some clients might require more than +1/3 and can implement their own TrustThreshold which can be passed into all relevant methods.

Implementations§

Source§

impl TrustThresholdFraction

Source

pub const ONE_THIRD: Self = _

Constant for a trust threshold of 1/3.

Source

pub const TWO_THIRDS: Self = _

Constant for a trust threshold of 2/3.

Source

pub fn new(numerator: u64, denominator: u64) -> Result<Self, Error>

Instantiate a TrustThresholdFraction if the given denominator and numerator are valid.

The parameters are valid iff 1/3 <= numerator/denominator <= 1. In any other case we return an error.

Source

pub fn numerator(&self) -> u64

The numerator of this fraction.

Source

pub fn denominator(&self) -> u64

The denominator of this fraction.
