Struct Derivation 

pub struct Derivation {
    pub store: String,
    pub facts: Vec<(String, String, String)>,
    pub unbound: bool,
}

What a candidate was distilled from: identities only, no source is named here. The sources are those the knowledge store bound each fact to, asked when the rule is written (provenance::prepare).

Fields

store: String

Project root as the knowledge store names it (the key of its facts).

facts: Vec<(String, String, String)>

(category, key, value) of every fact merged into the candidate.

unbound: bool

A part without a source on record was merged in (a diary entry): the rule is originless, whatever its facts are bound to.

Trait Implementations

impl Clone for Derivation

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Derivation

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

Formats the value using the given formatter.

impl Default for Derivation

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Derivation

impl PartialEq for Derivation

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

Equality operator ==.

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

Inequality operator !=.
