Trait Implementations

impl Clone for CardHeader

Performs copy-assignment from source.

impl Copy for CardHeader

impl Debug for CardHeader

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

Formats the value using the given formatter.

impl Default for CardHeader

fn default() -> Self

Returns the “default value” for a type.

impl Eq for CardHeader

impl PartialEq for CardHeader

fn eq(&self, other: &CardHeader) -> 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.
