    fn unpack_account_mint(account_data: &[u8]) -> Option<&Pubkey> { ... }
}

A trait for token Account structs to enable efficiently unpacking various fields without unpacking the complete state.

Required Methods

fn valid_account_data(account_data: &[u8]) -> bool

Check if the account data is a valid token account

Provided Methods

fn unpack_account_owner_unchecked(account_data: &[u8]) -> &Pubkey

Call after account length has already been verified to unpack the account owner

fn unpack_account_mint_unchecked(account_data: &[u8]) -> &Pubkey

Call after account length has already been verified to unpack the account mint

fn unpack_pubkey_unchecked(account_data: &[u8], offset: usize) -> &Pubkey

Call after account length has already been verified to unpack a Pubkey at the specified offset. Panics if account_data.len() is less than PUBKEY_BYTES

fn unpack_account_owner(account_data: &[u8]) -> Option<&Pubkey>

Unpacks an account’s owner from opaque account data.

fn unpack_account_mint(account_data: &[u8]) -> Option<&Pubkey>

Unpacks an account’s mint from opaque account data.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
