Struct on_change

pub struct on_change();

Lens for the field on_change on VirtualList.

Implementations

impl on_change

pub const fn new() -> on_change

Creates a new lens for the field on_change on VirtualList. Use VirtualList::on_change instead.

Trait Implementations

impl Clone for on_change

fn clone(&self) -> on_change

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for on_change

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

Formats the value using the given formatter.

impl Hash for on_change

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

where H: Hasher,

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 Lens for on_change

type Source = VirtualList

type Target = Option<Box<dyn Fn(&mut EventContext<'_>, Range<usize>)>>

fn view<'a>( &self, source: &'a VirtualList, ) -> Option<LensValue<'a, <on_change as Lens>::Target>>

impl PartialEq for on_change

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