Enum LockKind 

pub enum LockKind {
    SingleInstance,
    Allocation,
}

Which of the two host locks.

Variants

SingleInstance

Held for the whole life of the agent process. One holder per host means one reconciler per host.

Allocation

Held only while one runtime is being created, so that two concurrent allocations cannot both read the same headroom and both use it.

Implementations

impl LockKind

pub const fn file_name(self) -> &'static str

The file this lock lives in, inside state/.

pub const fn description(self) -> &'static str

How to name this lock to an operator.

pub const fn advice(self) -> &'static str

What an operator who lost the race should do about it. Present because “the lock is held” is a statement and not yet an instruction.
