Struct sp1_core::bytes::ByteChip

source · 
pub struct ByteChip<F>(/* private fields */);
Expand description

A chip for computing byte operations.

The chip contains a preprocessed table of all possible byte operations. Other chips can then use lookups into this table to compute their own operations.
