Enum ExtensionValue 

pub enum ExtensionValue {
    String(String),
    Integer(i64),
    Float(f64),
    Boolean(bool),
    Reference(i32),
    Expression(RawExpression),
}

Represents a value in extension arguments

Variants

String(String)

String literal value

Integer(i64)

Integer literal value

Float(f64)

Float literal value

Boolean(bool)

Boolean literal value

Reference(i32)

Field reference ($0, $1, etc.)

Expression(RawExpression)

Expression (function call, etc.) — not yet fully supported, hence the private interface.
