Enum Durability 

#[repr(u32)]
pub enum Durability {
    Volatile = 0,
    Transient = 1,
    Persistent = 2,
}

Where the substrate stores bytes for the substrate’s contract with the durability knob.

Variants

Volatile = 0

In-process anonymous memory; data evaporates on process exit.

Transient = 1

Cross-process RAM-resident shared memory; survives the producer’s exit if another holder keeps the named region alive, but is not on disk.

Persistent = 2

File-backed mmap; the bytes hit the page cache and can persist to disk via flush.
