Enum WritePrecondition 

pub enum WritePrecondition {
    None,
    IfAbsent,
    IfMatch(ResourceVersion),
}

Version precondition applied to a write operation.

Examples

use qubit_fs::write::WritePrecondition;

assert!(matches!(WritePrecondition::None, WritePrecondition::None));

Variants

None

Do not require a version precondition.

IfAbsent

Require that no destination exists.

IfMatch(ResourceVersion)

Require the destination to have the supplied version.

Tuple Fields

0: ResourceVersion

Resource version that must match the current destination.
