    // Required method

}

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", so this trait is not object safe.
