Struct langchain_rust::schemas::document::Document

pub struct Document {
    pub page_content: String,
    pub metadata: HashMap<String, Value>,
    pub score: f64,
}

The Document struct represents a document with content, metadata, and a score. The page_content field is a string that contains the content of the document. The metadata field is a HashMap where the keys represent metadata properties and the values represent property values. The score field represents a relevance score for the document and is a floating point number.

Usage

let my_doc = Document::new("This is the document content.".to_string())
   .with_metadata({
      let mut metadata = HashMap::new();
      metadata.insert("author".to_string(), json!("John Doe"));
      metadata
  })
   .with_score(0.75);

Fields

page_content: String

metadata: HashMap<String, Value>

score: f64
