Struct Expression 

pub struct Expression { /* private fields */ }

Parsed JSONata expression wrapper.

Examples

let expr = async_jsonata_rust::Parser::new().parse("Account.Order[0]")?;
assert_eq!(expr.source(), "Account.Order[0]");

Implementations

impl Expression

pub fn source(&self) -> &str

Returns original JSONata expression source.

Examples

let expr = async_jsonata_rust::Parser::new().parse("1")?;
assert_eq!(expr.source(), "1");

examples/basic_eval.rs (line 7)

fn main() {
    let parser = Parser::new();
    match parser.parse("Account.Order[0].Product") {
        Ok(expr) => {
            println!("Source: {}", expr.source());
            println!("AST type: {}", expr.ast()["type"]);
        }
        Err(err) => {
            eprintln!("{}: {}", err.code(), err.message());
            std::process::exit(1);
        }
    }
}

pub fn ast(&self) -> &Value

Returns parsed AST in JSON representation.

Examples

let expr = async_jsonata_rust::Parser::new().parse("1")?;
assert_eq!(expr.ast()["type"], "number");

Examples found in repository

examples/basic_eval.rs (line 8)

fn main() {
    let parser = Parser::new();
    match parser.parse("Account.Order[0].Product") {
        Ok(expr) => {
            println!("Source: {}", expr.source());
            println!("AST type: {}", expr.ast()["type"]);
        }
        Err(err) => {
            eprintln!("{}: {}", err.code(), err.message());
            std::process::exit(1);
        }
    }
}

pub fn into_ast(self) -> Value

Consumes wrapper and returns AST value.

Examples

let expr = async_jsonata_rust::Parser::new().parse("1")?;
let ast = expr.into_ast();
assert!(ast.is_object());
