Struct Location

pub struct Location {
    pub row: u32,
    pub col: u32,
}

Location of an Expression in a Rego query.

// Create engine and evaluate "  \n  1 + 2".
let results = Engine::new().eval_query("  \n  1 + 2".to_string(), false)?;

// Fetch the location for the expression.
let loc = &results.result[0].expressions[0].location;

assert_eq!(loc.row, 2);
assert_eq!(loc.col, 3);

Trait Implementations

impl Clone for Location

fn clone(&self) -> Location

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Location

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

Formats the value using the given formatter.

impl PartialEq for Location

fn eq(&self, other: &Location) -> 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 Location

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Location
