Struct glib::value::SendValue

#[repr(transparent)]
pub struct SendValue(_);

A version of Value for storing Send types, that implements Send itself.

See the module documentation for more details.

Implementations

impl SendValue

pub fn into_raw(self) -> GValue

Consumes SendValue and returns the corresponding GValue.

Methods from Deref<Target = Value>

pub fn get<'a, T>(
    &'a self
) -> Result<T, <<T as FromValue<'_>>::Checker as ValueTypeChecker>::Error> where
    T: FromValue<'a>, 

Tries to get a value of type T.

Returns Ok if the type is correct.

pub fn is<T: StaticType>(&self) -> bool

Returns true if the type of the value corresponds to T or is a sub-type of T.

pub fn type_(&self) -> Type

Returns the type of the value.

pub fn transform<T: ValueType>(&self) -> Result<Value, BoolError>

Tries to transform the value into a value of the target type Tries to cast the contents of self into a type appropriate to store in dest_value, e.g. to transform a G_TYPE_INT value into a G_TYPE_FLOAT value. Performing transformations between value types might incur precision lossage. Especially transformations into strings might reveal seemingly arbitrary results and shouldn’t be relied upon for production code (such as rcfile value or object property serialization).

dest_value

Target value.

Returns

Whether a transformation rule was found and could be applied. Upon failing transformations, dest_value is left untouched.

Trait Implementations

impl Clone for SendValue

fn clone(&self) -> SendValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SendValue

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

Formats the value using the given formatter.

impl Deref for SendValue

type Target = Value

The resulting type after dereferencing.

fn deref(&self) -> &Value

Dereferences the value.

impl<'a, T: ?Sized + ToSendValue> From<&'a T> for SendValue

fn from(value: &'a T) -> Self

Performs the conversion.

impl From<SendValue> for Value

fn from(value: SendValue) -> Self

Performs the conversion.
