Struct Provenance 

pub struct Provenance {
    pub extractor: String,
    pub evidence: EvidenceKind,
    pub confidence: Confidence,
    pub span: Option<SourceSpan>,
    pub detail: Option<String>,
}

Fields

extractor: String

evidence: EvidenceKind

confidence: Confidence

span: Option<SourceSpan>

detail: Option<String>

Implementations

impl Provenance

pub fn new( extractor: impl Into<String>, evidence: EvidenceKind, confidence: Confidence, ) -> Result<Provenance, GraphError>

Creates evidence provenance with a non-empty extractor identity.

Errors

Returns an error when the extractor is empty.

pub fn with_span(self, span: SourceSpan) -> Provenance

pub fn with_detail(self, detail: impl Into<String>) -> Provenance

Trait Implementations

impl Clone for Provenance

fn clone(&self) -> Provenance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Provenance

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Provenance

fn deserialize<__D>( __deserializer: __D, ) -> Result<Provenance, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Provenance

impl Hash for Provenance

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

where __H: Hasher,

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 Ord for Provenance

fn cmp(&self, other: &Provenance) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Provenance

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Provenance

fn partial_cmp(&self, other: &Provenance) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Provenance

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
