Enum GroupOrigin 

#[non_exhaustive]
pub enum GroupOrigin {
    User,
    Programmatic,
}

Who changed the grouping or the expansion, so a subscriber that keeps them itself and calls set_group_by or set_expanded can avoid a feedback loop.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

User

The group panel, a chevron, a key, a menu command or an Action.

Programmatic

A call of the grid API (set_group_by, set_view, set_expand_depth, set_expanded), or a restored layout.

Trait Implementations

impl Clone for GroupOrigin

fn clone(&self) -> GroupOrigin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupOrigin

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

Formats the value using the given formatter.

impl PartialEq for GroupOrigin

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