Struct HalDoc 

pub struct HalDoc {
    pub docid: String,
    pub label_s: Option<String>,
    pub uri_s: Option<String>,
    pub title_s: Option<Vec<String>>,
    pub auth_full_name_s: Option<Vec<String>>,
    pub produced_date_s: Option<String>,
    pub doc_type_s: Option<String>,
    pub extra: Map<String, Value>,
}

A single document returned by a HAL search.

HAL is a Solr index with a very large, evolving schema. Only the most common fields are typed here; any other field requested through SearchQuery::fields is preserved in HalDoc::extra.

Fields

docid: String

The HAL internal document identifier.

HAL returns this either as a number or as a string depending on the endpoint and version; it is always normalised to a String here.

label_s: Option<String>

A ready-to-display citation-style label (default field of a basic search).

uri_s: Option<String>

The canonical URI of the document on HAL (e.g. https://hal.science/…).

title_s: Option<Vec<String>>

The document title(s). Requested with fl=title_s.

auth_full_name_s: Option<Vec<String>>

The full names of the authors. Requested with fl=authFullName_s.

produced_date_s: Option<String>

The production date, as a string (e.g. 2026-06-04). Requested with fl=producedDate_s.

doc_type_s: Option<String>

The document type (e.g. ART, COMM, THESE). Requested with fl=docType_s.

extra: Map<String, Value>

Any other field returned by HAL but not modelled above.
