Struct wgpu_core::snatch::SnatchLock

pub struct SnatchLock {
    lock: RwLock<()>,
}

A Device-global lock for all snatchable data.

Fields

lock: RwLock<()>

Implementations

impl SnatchLock

pub unsafe fn new(rank: LockRank) -> Self

The safety of Snatchable::get and Snatchable::snatch rely on their using of the right SnatchLock (the one associated to the same device). This method is unsafe to force force sers to think twice about creating a SnatchLock. The only place this method should be called is when creating the device.

pub fn read(&self) -> SnatchGuard<'_>

Request read access to snatchable resources.

pub fn write(&self) -> ExclusiveSnatchGuard<'_>

Request write access to snatchable resources.

This should only be called when a resource needs to be snatched. This has a high risk of causing lock contention if called concurrently with other wgpu work.
