Enum ListModelChange 

pub enum ListModelChange<K> {
    RowsInserted {
        index: usize,
        count: usize,
    },
    RowsRemoved {
        index: usize,

    RowsChanged {

    },
    Reset,
}

One already-applied change to a ListModel. Structural variants retain mounted delegates by stable key; Self::RowsChanged rebuilds only the named rows.

Trait Implementations

impl<K> Clone for ListModelChange<K>

where K: Clone,

fn clone(&self) -> ListModelChange<K>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K> Debug for ListModelChange<K>

where K: Debug,

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

Formats the value using the given formatter.

impl<K> PartialEq for ListModelChange<K>

where K: PartialEq,

fn eq(&self, other: &ListModelChange<K>) -> 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.
