Trait Implementations

impl<'a> Clone for KeyedAccount<'a>

fn clone(&self) -> KeyedAccount<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for KeyedAccount<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<&'a (&'a Pubkey, &'a RefCell<AccountSharedData>)> for KeyedAccount<'a>

fn from(
    (key, account): &'a (&'a Pubkey, &'a RefCell<AccountSharedData>)
) -> Self

Converts to this type from the input type.

impl<'a> From<(&'a Pubkey, &'a RefCell<AccountSharedData>)> for KeyedAccount<'a>

fn from((key, account): (&'a Pubkey, &'a RefCell<AccountSharedData>)) -> Self

Converts to this type from the input type.

impl<'a> From<(&'a Pubkey, bool, &'a RefCell<AccountSharedData>)> for KeyedAccount<'a>

fn from(
    (key, is_signer, account): (&'a Pubkey, bool, &'a RefCell<AccountSharedData>)
) -> Self

Converts to this type from the input type.

impl<'a> PartialEq<KeyedAccount<'a>> for KeyedAccount<'a>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, T> State<T> for KeyedAccount<'a>where
    T: Serialize + DeserializeOwned,

fn state(&self) -> Result<T, InstructionError>

fn set_state(&self, state: &T) -> Result<(), InstructionError>
