Implementations

impl Ast

pub fn parse(query: &str) -> Result<Vec<Ast>>

pub fn to_sql(&self, dialect: &dyn ToQuery) -> Result<String>

Trait Implementations

impl Clone for Ast

fn clone(&self) -> Ast

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ast

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

Formats the value using the given formatter.

impl PartialEq for Ast

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

Tests for self and other values to be equal, and is used by ==.

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

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