}

Information on a precompiled program

Fields

program_id: Pubkey

Program id

feature: Option<Pubkey>

Feature to enable on, None indicates always enabled

verify_fn: fn(&[u8], &[&[u8]], &FeatureSet) -> Result<(), PrecompileError>

Verification function

Implementations

impl Precompile

pub fn new( program_id: Pubkey, feature: Option<Pubkey>, verify_fn: fn(&[u8], &[&[u8]], &FeatureSet) -> Result<(), PrecompileError>, ) -> Precompile

Creates a new Precompile

pub fn check_id<F>(&self, program_id: &Pubkey, is_enabled: F) -> bool

where F: Fn(&Pubkey) -> bool,

Check if a program id is this precompiled program

pub fn verify( &self, data: &[u8], instruction_datas: &[&[u8]], feature_set: &FeatureSet, ) -> Result<(), PrecompileError>

Verify this precompiled program
