StoreSnapshot

rust_sanitize::store

Struct StoreSnapshot 

Source 
pub struct StoreSnapshot(/* private fields */);
Expand description

An opaque cursor into the MappingStore insertion sequence.

Obtained from MappingStore::snapshot and passed to MappingStore::iter_since. Using a dedicated type prevents accidentally passing an unrelated usize (a count, an index, a capacity) to iter_since, which would silently yield the wrong subset of entries.

Breaking change in 0.13.0: MappingStore::snapshot previously returned usize; it now returns StoreSnapshot. Call sites should change store.snapshot() → the new type and iter_since(n) → iter_since(snap). To iterate all entries use StoreSnapshot::start instead of the literal 0.

Implementations§

Source§

impl StoreSnapshot

Source

pub fn start() -> Self

A snapshot representing the beginning of the store (before any insertions). Passing this to MappingStore::iter_since yields every entry in the store — equivalent to the former iter_since(0).
