Struct Provenance 

pub struct Provenance {
    pub rule_id: Option<String>,
    pub source_file: Option<String>,
    pub span: Option<SourceSpan>,
    pub attributes: Vec<(String, String)>,
}

Provenance information tracking the origin of an IR node

Fields

rule_id: Option<String>

Source rule ID or identifier

source_file: Option<String>

Source file information

span: Option<SourceSpan>

Source span

attributes: Vec<(String, String)>

Additional metadata as key-value pairs

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

Formats the value using the given formatter.

impl Default for Provenance

fn default() -> Self

Returns the “default value” for a type.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Provenance

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Provenance

impl StructuralPartialEq for Provenance
