Enum UiOptions

pub enum UiOptions {
    None,
    SplitActionBarWhenNarrow,
}

Extra options for an activity’s UI.

Variants

None

No extra UI options. This is the default

SplitActionBarWhenNarrow

Add a bar at the bottom of the screen to display action items in the app bar (also known as the action bar), when constrained for horizontal space (such as when in portrait mode on a handset). Instead of a small number of action items appearing in the app bar at the top of the screen, the app bar is split into the top navigation section and the bottom bar for action items. This ensures a reasonable amount of space is made available not only for the action items, but also for navigation and title elements at the top. Menu items are not split across the two bars; they always appear together.

Trait Implementations

impl Clone for UiOptions

fn clone(&self) -> UiOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UiOptions

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

Formats the value using the given formatter.

impl Default for UiOptions

fn default() -> UiOptions

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UiOptions

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UiOptions

fn eq(&self, other: &UiOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

const 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 UiOptions

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl YaDeserialize for UiOptions

fn deserialize<R: Read>(reader: &mut Deserializer<R>) -> Result<Self, String>

impl YaSerialize for UiOptions

fn serialize<W: Write>(&self, writer: &mut Serializer<W>) -> Result<(), String>

fn serialize_attributes( &self, source_attributes: Vec<OwnedAttribute>, source_namespace: Namespace, ) -> Result<(Vec<OwnedAttribute>, Namespace), String>
