Enum CheckState 

pub enum CheckState {
    Unchecked,
    Checked,
    Indeterminate,
}

Variants

Unchecked

The checkbox is unchecked (no fill, no mark).

Checked

The checkbox is fully checked (filled with a check mark).

Indeterminate

Some but not all descendants are checked; shown as a dash or partial fill.

Implementations

impl CheckState

pub fn is_filled(self) -> bool

Whether the box shows a filled background (checked or indeterminate).

pub fn next_tristate(self) -> Self

Cycle to the next state: Unchecked → Checked → Indeterminate → Unchecked.

Trait Implementations

impl Clone for CheckState

fn clone(&self) -> CheckState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CheckState

impl Debug for CheckState

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

Formats the value using the given formatter.

impl Eq for CheckState

impl From<bool> for CheckState

fn from(checked: bool) -> Self

Converts to this type from the input type.

impl Hash for CheckState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CheckState

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