Enum MemorySource 

pub enum MemorySource {
    Agent,
    User,
    System,
    Import,
    Sync,
}

Enumerates the five values accepted by the memories.source CHECK constraint.

Adding a new variant requires:

1. Updating the DDL CHECK constraint in migrations/V001__init.sql.
2. Running a migration that backfills any pre-existing values (UPDATE memories SET source='agent' WHERE source NOT IN (...)).
3. Bumping crate::constants::CURRENT_SCHEMA_VERSION.

Variants

Agent

Mutated by an LLM agent (remember, edit, rename, body-enrich).

User

Mutated by a human operator.

System

Mutated by an internal migration or system job.

Import

Inserted by bulk import (ingest). Rows written before v1.2.0 may also come from the retired --mode claude-code / --mode codex frontends.

Sync

Inserted by an external sync job.

Implementations

impl MemorySource

pub const ALL: &'static [MemorySource]

Returns every variant as a static slice, useful for error messages and docs.

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

Returns the canonical snake_case string stored in the SQLite column.

The returned slice has 'static lifetime because all five values are ASCII literals known at compile time.

Trait Implementations

impl Clone for MemorySource

fn clone(&self) -> MemorySource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for MemorySource

impl Debug for MemorySource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MemorySource

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MemorySource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for MemorySource

impl Hash for MemorySource

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MemorySource

fn eq(&self, other: &MemorySource) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for MemorySource

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for MemorySource

impl TryFrom<&str> for MemorySource

Parses a stored memories.source string back into a typed variant.

Errors

Returns AppError::Validation when the input is not one of the five canonical values. The error message lists every accepted value so the caller can self-correct without consulting the schema.

type Error = AppError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for MemorySource

type Error = AppError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
