Struct Citation 

pub struct Citation {
    pub citation_type: Option<String>,
    pub url: Option<String>,
    pub title: Option<String>,
    pub cited_text: Option<String>,
    pub document_index: Option<u32>,
    pub document_title: Option<String>,
    pub extra: Map<String, Value>,
}

A citation attached to a TextBlock, linking generated text back to a source.

Anthropic emits several citation shapes — web_search_result_location, char_location, page_location, content_block_location, … — that share a type tag and overlapping fields. This models the fields consumers commonly render as typed optionals and preserves any remaining variant-specific fields (start/end indices, encrypted_index, …) verbatim in Citation::extra, so unmodeled or future shapes deserialize without loss.

Fields

citation_type: Option<String>

Citation variant tag, e.g. "web_search_result_location".

url: Option<String>

Source URL (web-search citations).

title: Option<String>

Human-readable source title.

cited_text: Option<String>

The span of source text being cited.

document_index: Option<u32>

Index of the source document (document-location citations).

document_title: Option<String>

Title of the source document.

extra: Map<String, Value>

Any additional location fields not modeled above, preserved verbatim.

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 Default for Citation

fn default() -> Citation

Returns the “default value” for a type.

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 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.
