Enum InvalidationReason 

pub enum InvalidationReason {
    Obsolete,
    Superseded,
    Conflicted,
    Incorrect,
    Duplicate,
    Forgotten,
    Manual,
}

Canonical invalidation reason enum.

The string representation (serde snake_case) is written to the invalidated_reason column. Rows from before this enum was introduced have free-text reasons — they parse as Manual when the text doesn’t match a known variant.

Back-compat guarantee: InvalidationReason::Manual is the catch-all so existing rows and any hand-typed reason strings keep deserialising cleanly.

Variants

Obsolete

The memory is no longer accurate / the described behaviour changed.

Superseded

A newer memory supersedes or refines this one.

Conflicted

This memory directly contradicts another accepted memory.

Incorrect

The memory was factually wrong.

Duplicate

An exact or near-exact duplicate of another memory exists.

Forgotten

Archived by the active-forgetting policy (low-usefulness + stale).

Manual

Manually invalidated by a human (default / catch-all).

Implementations

impl InvalidationReason

pub fn as_str(&self) -> &'static str

Return the canonical snake_case string written to the DB column.

pub fn from_db(s: &str) -> Self

Parse a free-text invalidated_reason column value into the best matching variant. Unknown / pre-taxonomy strings → Manual.
