Enum ScalarLit 

pub enum ScalarLit {
    Null,
    Bool(bool),
    Int(i64),
    Str(String),
    Json(String),
}

A literal usable as a const value or an enum member.

Variants

Null

JSON null.

Bool(bool)

JSON true/false.

Int(i64)

A signed 64-bit integer.

Str(String)

A UTF-8 string.

Json(String)

A composite value held as its canonical JSON serialization (minimal whitespace, declared key order); only that one spelling is accepted (see PROVENANCE.md).

impl Ord for ScalarLit

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,
