Enum espr::ast::BuiltInConstant

pub enum BuiltInConstant {
    Napier,
    Pi,
    Self_,
    Indeterminate,
}

Variants

Napier

CONST_E, Napier’s constant e = 2.71828 …

Pi

The ratio of a circle’s circumference to its diameter, π = 3.14159 …

Self_

SELF is not a constant, but behaves as one in every context in which it can appear.

Indeterminate

The indeterminate symbol ? stands for an ambiguous value. It is compatible with all data types.
