Trait Implementations

impl AccountValidation for Writer

impl Clone for Writer

fn clone(&self) -> Writer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Writer

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

Formats the value using the given formatter.

impl Discriminator for Writer

fn discriminator() -> u8

impl PartialEq for Writer

fn eq(&self, other: &Writer) -> 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 Writer

fn zeroed() -> Self

Calls zeroed.

impl Copy for Writer

impl Pod for Writer

impl StructuralPartialEq for Writer
