Struct fvm_shared::clock::QuantSpec

pub struct QuantSpec {
    pub unit: ChainEpoch,
    pub offset: ChainEpoch,
}

A spec for epoch quantization.

Fields

unit: ChainEpoch

The unit of quantization

offset: ChainEpoch

The offset from zero from which to base the modulus

Implementations

impl QuantSpec

pub fn quantize_up(&self, epoch: ChainEpoch) -> ChainEpoch

Rounds epoch to the nearest exact multiple of the quantization unit offset by offset % unit, rounding up.

This function is equivalent to unit * ceil(epoch - (offset % unit) / unit) + (offsetSeed % unit) with the variables/operations over real numbers instead of ints.

Precondition: unit >= 0

pub fn quantize_down(&self, epoch: ChainEpoch) -> ChainEpoch
