Struct Provenance 

pub struct Provenance {
    pub created_by: String,
    pub created_at: String,
    pub source_file: Option<String>,
    pub source_line: Option<usize>,
    pub modified_by: Option<String>,
    pub modified_at: Option<String>,
    pub derived_from: Vec<String>,
    pub notes: Option<String>,
}

Provenance information tracking the origin and history of a symbol.

Fields

created_by: String

Who created this symbol (user, system, or tool name)

created_at: String

When it was created (ISO 8601 timestamp)

source_file: Option<String>

Source file or location where it was defined

source_line: Option<usize>

Source line number

modified_by: Option<String>

Who last modified this symbol

modified_at: Option<String>

When it was last modified (ISO 8601 timestamp)

derived_from: Vec<String>

Derivation information (if this symbol was derived from others)

notes: Option<String>

Additional provenance notes

Implementations

impl Provenance

pub fn new(created_by: impl Into<String>, created_at: impl Into<String>) -> Self

Creates a new provenance record.

pub fn with_source(self, file: impl Into<String>, line: Option<usize>) -> Self

Sets the source file location.

pub fn mark_modified( &mut self, modified_by: impl Into<String>, modified_at: impl Into<String>, )

Marks this symbol as modified.

pub fn add_derivation(&mut self, source: impl Into<String>)

Adds a derivation source.

pub fn with_notes(self, notes: impl Into<String>) -> Self

Sets provenance notes.

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<'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 Display for Provenance

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

Formats the value using the given formatter.

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.
