Struct MemoryRelation 

pub struct MemoryRelation { /* private fields */ }

Why one remembered thing led to another.

This is not an entry with a link attached. The relation is the reason: an entry says what was decided or seen, and only the edges say how one thing came from another. A memory of nothing but entries can be read but not followed, and following is how a later session works out how and why something was done.

So why is not optional. A relation without one asserts that two things are connected while declining to say how, which is the shape of a guess written down as a fact.

Implementations

impl MemoryRelation

pub fn new( from: MemoryEntryId, to: MemoryEntryId, kind: MemoryRelationKind, why: impl Into<String>, confidence: MemoryConfidence, ) -> Result<Self, DomainError>

Relate from to to, saying how and how sure.

The endpoints need not both be written by the same call. An ending explains a decision taken an hour earlier, and a session that could only relate what it wrote in one breath could never record that. What it may not do is relate an entry to itself: nothing explains itself, and an edge that says so is a cycle a reader will follow forever.

pub fn from(&self) -> &MemoryEntryId

pub fn to(&self) -> &MemoryEntryId

pub const fn kind(&self) -> MemoryRelationKind

pub fn why(&self) -> &str

The reason, in one line.

pub const fn confidence(&self) -> MemoryConfidence
