Struct HashCache 

Source 
pub struct HashCache {
    pub hashed_mints: ArrayMap<Pubkey, [u8; 32], 5>,
    pub hashed_pubkeys: Vec<(Pubkey, [u8; 32])>,

Expand description

Context for caching hashed values to avoid recomputation

Fields§

§hashed_mints: ArrayMap<Pubkey, [u8; 32], 5>

Cache for mint hashes: (mint_pubkey, hashed_mint)

§hashed_pubkeys: Vec<(Pubkey, [u8; 32])>

Cache for pubkey hashes: (pubkey, hashed_pubkey)
