Struct SelectExpr 

Source 
pub struct SelectExpr {
    pub operand: Expr,
    pub field: String,
    pub test_only: bool,
}
Expand description

A field selection expression.

Select expressions access fields on objects or maps. They can represent either:

  • Field access: obj.field (when test_only is false)
  • Presence test: has(obj.field) (when test_only is true)

Fields§

§operand: Expr

The expression being selected from (the object).

§field: String

The name of the field being selected.

§test_only: bool

If true, this is a presence test rather than field access.
