#[repr(transparent)]
pub struct EventGroupRef<'a, System: KernelEventGroup>(_, _);
Expand description

Represents a single borrowed event group in a system.

This type is ABI-compatible with System::RawEventGroupId. It’s logically equivalent to &'a EventGroup but instead stores RawEventGroupId directly.

See EventGroup for the owned counterpart and the description of this kernel object. See EventGroupMethods for the operations provided by this handle type.
