Struct glib::value::AnyValue

pub struct AnyValue { /* private fields */ }

A container type that allows storing any 'static type that implements Any and Clone to be stored in a Value.

See the module documentation for more details.

Examples

use glib::prelude::*; // or `use gtk::prelude::*;`
use glib::{AnyValue, Value};

// Store a Rust string inside a Value
let v = AnyValue::new(String::from("123")).to_value();

// Retrieve the Rust String from the the Value again
let any_v = v.get::<&AnyValue>()
    .expect("Value did not actually contain an AnyValue");
assert_eq!(any_v.downcast_ref::<String>(), Some(&String::from("123")));

Implementations

impl AnyValue

pub fn new<T: Any + Clone + 'static>(val: T) -> Self

Create a new AnyValue from val

pub fn downcast<T: Any + Clone + 'static>(self) -> Result<T, Self>

Attempt the value to its concrete type.

Trait Implementations

impl Clone for AnyValue

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AnyValue

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

Formats the value using the given formatter.

impl Deref for AnyValue

type Target = dyn Any + 'static

The resulting type after dereferencing.

fn deref(&self) -> &dyn Any

Dereferences the value.

impl<'a> FromValueOptional<'a> for &'a AnyValue

unsafe fn from_value_optional(value: &'a Value) -> Option<Self>

impl SetValue for AnyValue

unsafe fn set_value(value: &mut Value, this: &Self)

impl StaticType for AnyValue

fn static_type() -> Type
