Enum AtomicityRequirement 

pub enum AtomicityRequirement {
    Required,
    Preferred,
    NotRequired,
}

Atomicity contract requested by an operation.

Examples

use qubit_fs::metadata::AtomicityRequirement;

assert_eq!(AtomicityRequirement::Preferred, AtomicityRequirement::default());

Variants

Required

Success must be atomic; unsupported guarantees fail before side effects.

Preferred

Prefer an atomic method but permit a reported non-atomic result.

NotRequired

Do not require atomicity, although an implementation may still use it.
