Enum CpuThreadExecution 

pub enum CpuThreadExecution {
    Idle,
    SharedScope,
    Active,
}

What CPU execution the current thread is inside.

An owner that serializes callers with a blocking lock (such as an eager runtime’s backend owner) must not wait on that lock while this thread holds a CPU execution permit: another thread may hold the owner and wait for the permit (#1946 F1).

Examples

use tenferro_cpu::{current_cpu_execution, CpuBackend, CpuThreadExecution};

assert_eq!(current_cpu_execution(), CpuThreadExecution::Idle);
let backend = CpuBackend::with_threads(1)?;
assert_eq!(backend.install(current_cpu_execution)?, CpuThreadExecution::Active);
let in_scope = backend.with_execution_scope(current_cpu_execution)?;
assert_eq!(in_scope, CpuThreadExecution::SharedScope);

Variants

Idle

No CPU execution holds a permit on this thread.

SharedScope

A shared execution scope holds a permit, and none of its operations is running: an operation or session may still be admitted under it.

Active

A CPU operation or session is running; nested entry is rejected.
