Enum Encoding 

pub enum Encoding {
    Record,
    Raw,
}

How a key’s value is encoded on disk.

The store keeps two encodings in one flat keyspace and distinguishes them by prefix alone. Mixing them is not a type error, it is a silent one: a raw scalar written into a Record namespace is skipped by scan_prefix with a warning, and a Record written over a raw scalar is unreadable by the getter that expects bytes. policy:mode did exactly this, colliding with policy:<slug> records so that setting the posture destroyed a policy.

This table is the invariant. Store debug-asserts against it, so a new key in the wrong namespace fails a test run rather than corrupting a store.

Variants

Record

msgpack-serialized Record. Written by put, read by get/scan_prefix.

Raw

Bare bytes whose meaning is prefix-specific: a timestamp, a counter, a config scalar, or a JSON blob. Written by put_raw, read by get_raw_bytes/scan_keys.

Implementations

impl Encoding

pub fn for_key(key: &str) -> Self

Infer a key’s value encoding from its prefix.

Unknown prefixes default to Record, which matches for_key defaulting to Immediate: a new knowledge namespace is the common case, and the assertion below turns a wrong guess into a failing test.
