Enum DocumentLaunchMode

pub enum DocumentLaunchMode {
    IntoExisting,
    Always,
    None,
    Never,
}

Four values which produce the following effects when the user opens a document with the application

Variants

IntoExisting

The system searches for a task whose base intent’s ComponentName and data URI match those of the launching intent. If the system finds such a task, the system clears the task, and restarts with the root activity receiving a call to onNewIntent(android.content.Intent). If the system does not find such a task, the system creates a new task.

Always

The activity creates a new task for the document, even if the document is already opened. This is the same as setting both the FLAG_ACTIVITY_NEW_DOCUMENT and FLAG_ACTIVITY_MULTIPLE_TASK flags.

None

The activity does not create a new task for the activity. This is the default value, which creates a new task only when FLAG_ACTIVITY_NEW_TASK is set. The overview screen treats the activity as it would by default: it displays a single task for the app, which resumes from whatever activity the user last invoked.

Never

This activity is not launched into a new document even if the Intent contains FLAG_ACTIVITY_NEW_DOCUMENT. Setting this overrides the behavior of the FLAG_ACTIVITY_NEW_DOCUMENT and FLAG_ACTIVITY_MULTIPLE_TASK flags, if either of these are set in the activity, and the overview screen displays a single task for the app, which resumes from whatever activity the user last invoked.

Trait Implementations

impl Clone for DocumentLaunchMode

fn clone(&self) -> DocumentLaunchMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DocumentLaunchMode

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

Formats the value using the given formatter.

impl Default for DocumentLaunchMode

fn default() -> DocumentLaunchMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DocumentLaunchMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DocumentLaunchMode

fn eq(&self, other: &DocumentLaunchMode) -> 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 DocumentLaunchMode

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 DocumentLaunchMode

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

impl YaSerialize for DocumentLaunchMode

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>
