znap
Znap framework's core library to create Solana actions
znap
is the core library that encompasses znap-macros
, znap-syn and other essential components for Solana actions programming.
znap
is responsible for coordinating the different modules and tools needed to parse, transform and generate code in Rust. By integrating znap-macros
and znap-syn
, znap
allows developers to take full advantage of Rust's capabilities to create Solana actions.
