Struct ParallelSha256Compression 

pub struct ParallelSha256Compression { /* private fields */ }

Parallel SHA-256 two-to-one compression for the inner nodes of a Merkle tree.

Groups of four independent compressions run through the interleaved four-way block kernel. A trailing group smaller than four compresses one node at a time. Every output byte equals compressing each node on its own with the scalar function.

Trait Implementations
