Enum libgir::library::ParameterScope

pub enum ParameterScope {
    None,
    Call,
    Async,
    Notified,
    Forever,
}

Annotation describing lifetime requirements / guarantees of callback parameters, that is callback itself and associated user data.

Variants

None

Parameter is not of callback type.

Call

Used only for the duration of the call.

Can be invoked multiple times.

Async

Used for the duration of the asynchronous call.

Invoked exactly once when asynchronous call completes.

Notified

Used until notified with associated destroy notify parameter.

Can be invoked multiple times.

Forever

Forever scope

Trait Implementations

impl Clone for ParameterScope

fn clone(&self) -> ParameterScope

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterScope

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

Formats the value using the given formatter.

impl Default for ParameterScope

fn default() -> ParameterScope

Returns the “default value” for a type.

impl FromStr for ParameterScope

type Err = String

The associated error which can be returned from parsing.

fn from_str(name: &str) -> Result<Self, String>

Parses a string s to return a value of this type.

impl PartialEq for ParameterScope

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