MemoryWrite

Struct MemoryWrite 

Source
pub struct MemoryWrite<'a> {
    pub scope: &'a str,
    pub kind: MemoryKind,
    pub anchor: Option<&'a str>,
    pub body: &'a str,
    pub confidence: Option<f64>,
    pub supersedes: Option<i64>,
}
Expand description

The values crate::Store::record_memory writes.

anchor is a node key; the blob and path stored alongside it are captured by the store from the graph at write time, so there is exactly one place that decides what an anchor’s evidence is. tree is captured the same way.

Fields§

§scope: &'a str

The scope to record.

§kind: MemoryKind

What kind of knowledge this is.

§anchor: Option<&'a str>

The node key to anchor to, if any. A key naming no node is accepted, and reads back as AnchorState::Vanished: recording a lesson about code that is already gone is a legitimate — often the most valuable — thing to do, and refusing it would be the prune rule wearing a different hat.

§body: &'a str

The prose.

§confidence: Option<f64>

The writer’s own confidence, if it has one.

§supersedes: Option<i64>

The record this one overrules, if any. Supersession is recorded here, explicitly, at the moment the successor is written — never inferred later from age.

Implementations§

Source§

impl MemoryWrite<'_>

Source

pub fn validate(&self) -> Result<(), MemoryError>

Validate a write, refusing a record that could not be stored or recalled.

§Errors

Returns MemoryError::InvalidScope, MemoryError::InvalidBody or MemoryError::InvalidConfidence, each naming what was actually wrong.
