Expand description

A lock.

Safety

This lock must uphold XOR mutability: at any give time either one exclusive guard or multiple shared guards can be handed out.

Note that the shared implementation does not actually have to be shared; it is just an optimization for implementations that support it.

Required Methods

Acquire an exclusive lock.

When called recursively, this function must panic, abort or deadlock.

If the previous guard was dropped during a panic, this function may or may not panic.

Acquire a shared lock.

When called recursively, this function may succeed, panic, abort or deadlock.

If the previous guard was dropped during a panic, this function may or may not panic.
