Trait Implementations

impl AccountValidation for Tape

fn assert<F>(&self, condition: F) -> Result<&Self, ProgramError>

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

impl Clone for Tape

fn clone(&self) -> Tape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tape

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

Formats the value using the given formatter.

impl Discriminator for Tape

fn discriminator() -> u8

impl PartialEq for Tape

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Zeroable for Tape

fn zeroed() -> Self

Calls zeroed.

impl Copy for Tape

impl Pod for Tape

impl StructuralPartialEq for Tape
