Struct SharedResources 

pub struct SharedResources(/* private fields */);

A window’s handle to the session’s resource registry — Core’s resources field. A font, image or sound registered through one is registered for every window in the session, and draws in all of them.

Implementations

impl SharedResources

pub fn add_image(&self, width: u32, height: u32, rgba: Vec<u8>) -> ImageId

Registers an RGBA image (width * height * 4 bytes).

pub fn remove_image(&self, id: ImageId) -> bool

Drops an image from the registry. Every window’s atlas forgets its blit at that window’s next frame, and a texture-backed one is dropped from the device by the next frame any window draws.

pub fn image_size(&self, id: ImageId) -> Option<(u32, u32)>

The pixel dimensions behind an image handle, if it is live.

pub fn add_sound(&self, bytes: Vec<u8>) -> SoundId

Registers a sound from its encoded file bytes.

pub fn has_sounds(&self) -> bool

Whether any sound is registered (see Resources::has_sounds).

pub fn sound(&self, id: SoundId) -> Option<Arc<[u8]>>

The encoded bytes behind a sound handle, if it is live. Cloning the Arc rather than lending it is what lets the registry be shared: the caller (an audio backend) holds the bytes, not the borrow.

pub fn font_family(&self, id: FontId) -> Option<String>

The registered family name behind a font handle, if it is live.

Trait Implementations

impl Clone for SharedResources

fn clone(&self) -> SharedResources

Returns a duplicate of the value.

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

Performs copy-assignment from source.
