Struct glib::value::TypedValue

#[repr(C)]
pub struct TypedValue<T>(_, _);

A statically typed Value.

It dereferences to Value and can be used everywhere Value references are accepted.

See the module documentation for more details.

Methods

impl<'a, T: FromValueOptional<'a> + SetValue> TypedValue<T>

pub fn get(&'a self) -> Option<T>

Returns the value.

Types that don't support a None value always return Some. See get_some.

pub fn get_some(&'a self) -> T where
    T: FromValue<'a>, 

Returns the value.

This method is only available for types that don't support a None value.

pub fn set<U: ?Sized + SetValueOptional>(&mut self, value: Option<&U>) where
    T: Borrow<U>, 

Sets the value.

This method is only available for types that support a None value.

pub fn set_none(&mut self) where
    T: SetValueOptional, 

Sets the value to None.

This method is only available for types that support a None value.

pub fn set_some<U: ?Sized + SetValue>(&mut self, value: &U) where
    T: Borrow<U>, 

Sets the value.

impl<'a, T: FromValueOptional<'a> + SetValue + Send> TypedValue<T>

pub fn into_send_value(self) -> SendValue

Methods from Deref<Target = Value>

pub fn downcast_ref<'a, T: FromValueOptional<'a> + SetValue>(
    &self
) -> Option<&TypedValue<T>>

Tries to downcast to a &TypedValue.

Returns Some(&TypedValue<T>) if the value carries a type corresponding to T and None otherwise.

pub fn get<'a, T: FromValueOptional<'a>>(
    &'a self
) -> Result<Option<T>, GetError>

Tries to get a possibly optional value of type T.

Returns Ok if the type is correct.

pub fn get_some<'a, T: FromValue<'a>>(&'a self) -> Result<T, GetError>

Tries to get a value of type T.

This method is only available for types that don't support a None value.

Returns Ok if the type is correct.

pub fn is<'a, T: FromValueOptional<'a> + SetValue>(&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: StaticType + SetValue>(&self) -> Option<Value>

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