Struct BackendRefreshSample 

pub struct BackendRefreshSample {
    pub epoch: MountEpoch,
    pub listings: BTreeMap<String, u64>,
    pub stamps: BTreeMap<String, u64>,
}

One explicit observation of a mounted backend that lacks a watch contract.

Listing and stamp keys are canonical absolute expression-tree paths. Their numeric values are backend-owned monotone or content-derived stamps; the calculator compares them for equality and never interprets their magnitude.

Fields

epoch: MountEpoch

Backend-wide generation.

listings: BTreeMap<String, u64>

Directory listing stamps by absolute directory path.

stamps: BTreeMap<String, u64>

Entry stamps by absolute entry path.

pub fn with_listing(self, path: impl Into<String>, stamp: u64) -> Self

Adds a directory listing stamp.
