Struct Durability 

pub struct Durability {
    pub tier: DurabilityTier,
    pub engine: Option<DurabilityEngine>,
    pub store: Option<String>,
    pub subjects: Vec<String>,
    pub rpo_seconds: Option<u32>,
    pub state_mb: Option<u32>,
}

A parsed yah.durability.* declaration. See WorkloadSpec::durability.

Fields

tier: DurabilityTier

engine: Option<DurabilityEngine>

Which engine’s tier vocabulary this is. Some exactly when DurabilityTier::ships_bytes — enforced by the accessor (R850-F1).

store: Option<String>

Object-store URL the copy lives at. Some exactly when DurabilityTier::ships_bytes — enforced by the accessor.

subjects: Vec<String>

Volume-relative paths of the database files this tier covers, in declaration order. Non-empty exactly when DurabilityTier::ships_bytes — enforced by the accessor (R850-F1).

Volume-relative, never absolute: the same string is joined onto the container’s mount target when read as documentation and onto /var/lib/yah/kamaji/volumes/<name> when a hydrate writes it. Each is also the object-store key suffix under Self::store, so the layout an operator sees in the bucket mirrors the layout on the volume.

rpo_seconds: Option<u32>

Declared recovery-point objective in seconds. DurabilityTier::Stream only; None there means turso_backup::stream::DEFAULT_RPO_TARGET.

state_mb: Option<u32>

Expected steady-state size of this workload’s state, in MiB — the input a cold-start-from-object-store estimate needs and cannot get anywhere else. resources.ephemeral_storage_mb is not it: that caps the writable layer and tmpfs, and a named volume is neither.

Declared, never measured. Any recovery-time figure derived from it inherits that, and must say so at the point it is printed.
