Trait Implementations

impl Clone for Sizing

fn clone(&self) -> Sizing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sizing

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

Formats the value using the given formatter.

impl Default for Sizing

fn default() -> Sizing

Returns the “default value” for a type.

impl PartialEq for Sizing

fn eq(&self, other: &Sizing) -> 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 Copy for Sizing

impl StructuralPartialEq for Sizing
