Struct Citation 

pub struct Citation {
    pub uri: String,
    pub accessed_at: String,
    pub hash: Option<String>,
    pub span: Option<SourceSpan>,
}

v0.7.0 Form 4 (issue #757) — fact-provenance citation envelope.

One entry inside Memory::citations. The shape mirrors common scholarly-citation needs while staying substrate-friendly:

• uri — URL, doc:<id> substrate pointer, or file:<path>. The validator (crate::validate::validate_citation) rejects bare strings; callers must use one of the typed schemes.
• accessed_at — RFC3339 timestamp at which the cited source was read by the agent. Captures the fact-grain “when did this claim become known to me” datum.
• hash — optional SHA-256 of the cited content. Lets a downstream verifier confirm the source has not drifted since capture.
• span — optional byte-range pinning the specific quote inside the cited body. Composes with Memory::source_span for atom-grain lineage (the parent’s span points into the source, the atom’s source_span points into the parent’s body).

Fields

uri: String

accessed_at: String

hash: Option<String>

span: Option<SourceSpan>

Trait Implementations

impl Clone for Citation

fn clone(&self) -> Citation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Citation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Citation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Citation

impl PartialEq for Citation

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Citation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
