Methods from Deref<Target = Value>

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

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

Tries to get a value of type T.

Returns Ok if the type is correct.

Tries to get a value of an owned type T.

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

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>(&self) -> Result<Value, BoolError>where T: ValueType,

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

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

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