Implementations

impl Keyword

pub fn as_str(&self) -> &'static str

Get the keyword as a string slice (lowercase)

pub fn is_aggregation(&self) -> bool

Check if this keyword is an aggregation operator

pub fn is_aggregation_with_param(&self) -> bool

Check if this keyword is an aggregation that takes a parameter

pub fn is_set_operator(&self) -> bool

Check if this keyword is a set operator

Trait Implementations

impl Clone for Keyword

fn clone(&self) -> Keyword

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Keyword

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

Formats the value using the given formatter.

impl Display for Keyword

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

Formats the value using the given formatter.

impl PartialEq for Keyword

fn eq(&self, other: &Keyword) -> 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.

impl Copy for Keyword
