Implementations

impl InternedStore

pub fn inspect_mmap_artifact( sdk_key: &str, ) -> Result<MmapArtifactSnapshot, StatsigErr>

Inspects the SDK-owned artifact without exposing its derived path or file identity.

V2 state uses the same committed-manifest identity validation as preload_mmap. The snapshot is informational and does not map or parse either archived config payload.

impl InternedStore

pub fn preload(data: &[u8]) -> Result<(), StatsigErr>

pub fn preload_multi(data: &[&[u8]]) -> Result<(), StatsigErr>

pub async fn fetch_and_write_mmap(sdk_key: &str) -> Result<(), StatsigErr>

Publishes a V2 mmap artifact selected by sdk_key.

On Unix, the finalized artifact is atomically published with mode 0644 so readers with unrelated UIDs can consume a read-only shared mount.

pub async fn fetch_and_write_mmap_with_specs_url( sdk_key: &str, specs_url: &str, ) -> Result<(), StatsigErr>

pub async fn fetch_and_write_mmap_with_specs_url_if_changed( sdk_key: &str, specs_url: &str, previous: Option<&MmapSyncCursor>, ) -> Result<MmapWriteOutcome, StatsigErr>

pub fn preload_mmap(sdk_key: &str) -> Result<(), StatsigErr>

pub fn mmap_reader_memory_snapshot() -> Result<Option<MmapReaderMemorySnapshot>, StatsigErr>

Reports memory accounting for the currently loaded mmap reader.

Returns None before a reader has been installed. Linux reports RSS, PSS, private dirty, deleted mapping bytes, and VMA segment count for the exact retained mapping by reading /proc/self/smaps, so callers should sample infrequently. Other platforms leave those optional fields unset.

pub fn preload_mmap_with_options( sdk_key: &str, options: &MmapPreloadOptions, ) -> Result<MmapPreloadReport, StatsigErr>

Preloads the committed artifact with optional eager reader work and reports the selected compatibility-reader format.
