}Expand description
Trait implemented by all expression types. Most users will want to store an Expr instead.
Required Methods§
sourcefn children(&self) -> Vec<Box<dyn AnyExpr>>
fn children(&self) -> Vec<Box<dyn AnyExpr>>
Returns the child expressions.
For example, the child expressions of x + y would be x and y.
Provided Methods§
sourcefn shape_hint(&self) -> ShapeHint<'_>
fn shape_hint(&self) -> ShapeHint<'_>
Returns a hint about the expression’s shape.
