[][src]Struct wayland_commons::utils::UserData

pub struct UserData { /* fields omitted */ }

A wrapper for user data, able to store any type, and correctly handling access from a wrong thread

Methods

impl UserData[src]

pub fn new_threadsafe<T: Send + Sync + 'static>(value: T) -> UserData[src]

Create a new UserData using a threadsafe type

Its contents can be accessed from any thread.

pub fn new<T: 'static>(value: T) -> UserData[src]

Create a new UserData using a non-threadsafe type

Its contents can only be accessed from the same thread as the one you are creating it.

pub fn empty() -> UserData[src]

Create a new UserData containing nothing

pub fn get<T: 'static>(&self) -> Option<&T>[src]

Attempt to access the wrapped user data

Will return None if either:

  • The requested type T does not match the type used for construction
  • This UserData has been created using the non-threadsafe variant and access is attempted from an other thread than the one it was created on
