pub fn set_flags(&mut self, flags: BufferFlags)
Set the flags for this buffer.
sourcepub fn flags(&self) -> BufferFlags
pub fn flags(&self) -> BufferFlags
Get the flags for this buffer.
sourcepub fn set_cluster_level(&mut self, cluster_level: BufferClusterLevel)
pub fn set_cluster_level(&mut self, cluster_level: BufferClusterLevel)
Set the cluster level of the buffer.
