Struct glib::value::SendValue

pub struct SendValue { /* private fields */ }

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

See the module documentation for more details.

GLib type: Inline allocated boxed type with stack copy semantics.

Implementations

impl SendValue

pub fn as_ptr(&self) -> *mut GValue

pub unsafe fn from_glib_ptr_borrow<'a>(ptr: *const GValue) -> &'a Self

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut<'a>(ptr: *mut GValue) -> &'a mut Self

Borrows the underlying C value mutably.

impl SendValue

pub fn into_raw(self) -> GValue

Consumes SendValue and returns the corresponding GValue.

pub fn from_owned<T: Send + Into<Value> + ?Sized>(t: T) -> Self

Methods from Deref<Target = Value>

pub fn as_ptr(&self) -> *mut GValue

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 get_owned<T>( &self, ) -> Result<T, <<T as FromValue<'_>>::Checker as ValueTypeChecker>::Error>

where T: for<'b> FromValue<'b> + 'static,

Tries to get a value of an owned type T.

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 is_type(&self, type_: Type) -> bool

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

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. 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.

dest_value

Target value.

Returns

pub fn transform_with_type(&self, type_: Type) -> Result<Value, BoolError>

Tries to transform the value into a value of the target type
