SqliteOpaqueObjectStoreV1

Struct SqliteOpaqueObjectStoreV1 

Source
pub struct SqliteOpaqueObjectStoreV1(/* private fields */);
Expand description

Canonical opaque objects, independent of application schemas and filesystem publication.

Implementations§

Source§

impl SqliteOpaqueObjectStoreV1

Source

pub fn changes( &self, installation: &str, generation: &str, after: u64, through: u64, limit: usize, max_bytes: usize, ) -> R<ObjectChangesPageV1>

Reads current values for a fixed change range, deduplicated by key within the range. generation must match the prior head; source replacement fails closed. Metadata is admitted before BLOB reads. Too small a budget fails instead of returning a stalled page.

Source

pub fn scan( &self, installation: &str, after: Option<&str>, limit: usize, max_bytes: usize, ) -> R<ObjectsPageV1>

Scans current records; callers must catch up changes after the initial scan head.

Source§

impl SqliteOpaqueObjectStoreV1

Source

pub fn head(&self) -> R<ObjectHeadV1>

Reads generation/revision without loading any envelope or altering the database.

Source

pub fn get( &self, installation: &str, key: &str, ) -> R<Option<OpaqueObjectRecordV1>>

Reads and hash-checks one bounded current record; absent is distinct from deleted.
