Struct glin::Fence

pub struct Fence { /* fields omitted */ }

A fence can be used to wait until a gpu process has finished

To use it create a new one and then wait on it

The msot common pattern is to wait on it on the next frame or even later, for example for double or triple buffering with manual sync

Implementations

impl Fence

pub fn wait(self) -> Result<()>

Wait for all the gl calls before this fence was created to finish

Waiting on the fence consumes it so if it’s stored in a struct you might need to use an option with take to replace the current fence with None before replacing it again with a new one.

pub fn try_wait(&mut self, flags: GLenum, duration: Duration) -> Result<()>

Try waiting duration for all the gl calls before this fence was created to finish
