Implementations

impl IdedExpr

pub fn references(&self) -> ExpressionReferences<'_>

Returns a set of all variables and functions referenced in the expression.

Example

let expression = Parser::new().parse("foo && size(foo) > 0").unwrap();
let references = expression.references();

assert!(references.has_variable("foo"));
assert!(references.has_function("size"));

Trait Implementations

impl Clone for IdedExpr

fn clone(&self) -> IdedExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdedExpr

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

Formats the value using the given formatter.

impl Default for IdedExpr

fn default() -> IdedExpr

Returns the “default value” for a type.

impl PartialEq for IdedExpr

fn eq(&self, other: &IdedExpr) -> 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.
