Struct dusk_poseidon::tree::PoseidonAnnotation

source · [−]

pub struct PoseidonAnnotation { /* private fields */ }

Expand description

A microkelvin annotation with the minimum data for a functional poseidon tree

The recommended usage for extended annotations for poseidon trees is to have this structure as attribute of the concrete annotation, and reflect the borrows of the cardinality and scalar to the poseidon annotation implementation.
