Lit is mostly inspired by SQL-92 Literals standard and PartiQL specification. See section 5.3 in the following: https://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt and Section 2 of the following (Figure 1: BNF Grammar for PartiQL Values): https://partiql.org/assets/PartiQL-Specification.pdf

Trait Implementations

impl Clone for Lit

fn clone(&self) -> Lit

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Lit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Lit> for Lit

fn eq(&self, other: &Lit) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Visit for Lit

fn visit<'v, V>(&'v self, v: &mut V) -> Traversewhere V: Visitor<'v>,
