Enum zng::focus::DirectionalNav

pub enum DirectionalNav {
    None,
    Continue,
    Contained,
    Cycle,
}

Directional navigation configuration of a focus scope.

See the module level for an overview of directional navigation.

Variants

None

Arrows can move into the scope, but does not move the focus inside the scope.

Continue

Arrows move the focus through the scope continuing out of the edges.

Contained

Arrows move the focus inside the scope only, stops at the edges.

Cycle

Arrows move the focus inside the scope only, cycles back to opposite edges.

Trait Implementations

impl Clone for DirectionalNav

fn clone(&self) -> DirectionalNav

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DirectionalNav

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DirectionalNav

fn deserialize<__D>( __deserializer: __D, ) -> Result<DirectionalNav, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DirectionalNav

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 PartialEq for DirectionalNav

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

impl Serialize for DirectionalNav

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
