# Struct glib::value::TypedValue [−] [src]

    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>`
[src]

#### `pub fn get(&'a self) -> Option<T>`
[src]

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>,`
[src]

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>,`
[src]

Sets the value.

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

#### `pub fn set_none(&mut self) where
T: SetValueOptional,`
[src]

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>,`
[src]

Sets the value.

## Methods from Deref<Target = Value>

#### `pub fn get<'a, T: FromValueOptional<'a>>(&'a self) -> Option<T>`
[src]

Tries to get a value of type `T`.

Returns `Some` if the type is correct and the value is not `None`.

This function doesn't distinguish between type mismatches and correctly typed `None` values. Use `downcast` or `is` for that.

#### `pub fn is<'a, T: FromValueOptional<'a> + SetValue>(&self) -> bool`
[src]

Returns `true` if the type of the value corresponds to `T`.

#### `pub fn type_(&self) -> Type`
[src]

Returns the type of the value.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
