Enum AggregateMode 

pub enum AggregateMode {
    None,
    DescendantsDriveAncestors,
}

How a parent’s CheckState relates to its descendants.

Variants

None

Each node owns its state independently; parent states do not reflect their descendants and cascades do not occur.

DescendantsDriveAncestors

All-checked → Checked; all-unchecked → Unchecked; mixed → Indeterminate. Toggling a parent cascades Checked/Unchecked to all descendants and recomputes every ancestor. This is the default and corresponds to the “Outlook folder selection” tristate pattern.

Trait Implementations

impl Clone for AggregateMode

fn clone(&self) -> AggregateMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AggregateMode

impl Debug for AggregateMode

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

Formats the value using the given formatter.

impl Default for AggregateMode

fn default() -> AggregateMode

Returns the “default value” for a type.

impl Eq for AggregateMode

impl PartialEq for AggregateMode

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