Trait Implementations

impl Clone for FocusState

fn clone(&self) -> FocusState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FocusState

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

Formats the value using the given formatter.

impl Default for FocusState

fn default() -> FocusState

Returns the “default value” for a type.

impl PartialEq for FocusState

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

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

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