Struct SnapshotView 

pub struct SnapshotView { /* private fields */ }

A frozen, Send view of one store’s live entries at a single instant.

Implementations

impl SnapshotView

pub fn each<F: FnMut(&[u8], &Value, Option<u64>)>(&self, f: F)

Visit every entry as (key, &value, ttl_ms) — the same shape as Store::snapshot_each, so serializers take either source.

pub fn each_hash_ttl<F: FnMut(&[u8], &[u8], u64)>(&self, f: F)

Visit the frozen hash field TTLs.

pub fn len(&self) -> usize

Number of entries frozen in the view.

pub fn is_empty(&self) -> bool

Whether the view holds zero entries.

pub fn materialize_cold(&self, key: &[u8], v: &Value) -> Option<Value>

Decode a cold stub’s record against the view’s pinned vlog files into a fresh hot Value — the serializer-thread read path: no store access, no promotion, memory bound = this one value. None when v is hot. A stub naming an unpinned file, a failed read, or a bad decode is a process bug (the vlog is per-boot and this process pinned every file at collect time) — surfaced loudly, never healed silently.

pub fn row_seg_files(&self) -> Vec<(u32, String)>

The frozen row segments’ (seq, file) identities.
