Implementations

impl Nothing

pub fn new() -> Self

Trait Implementations

impl Clone for Nothing

fn clone(&self) -> Nothing

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Nothing

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

Formats the value using the given formatter.

impl Default for Nothing

fn default() -> Self

Returns the “default value” for a type.

impl Matchable for Nothing

fn match_segments( &self, _segments: &[ErasedSegment], idx: u32, _parse_context: &mut ParseContext<'_>, ) -> Result<MatchResult, SQLParseError>

fn mk_from_segments(&self, segments: Vec<ErasedSegment>) -> ErasedSegment

fn get_type(&self) -> SyntaxKind

fn match_grammar(&self) -> Option<Arc<dyn Matchable>>

fn hack_eq(&self, rhs: &Arc<dyn Matchable>) -> bool

fn is_optional(&self) -> bool

fn simple( &self, parse_context: &ParseContext<'_>, crumbs: Option<Vec<&str>>, ) -> Option<(AHashSet<String>, SyntaxSet)>

fn cache_key(&self) -> MatchableCacheKey

fn copy( &self, _insert: Option<Vec<Arc<dyn Matchable>>>, _at: Option<usize>, _before: Option<Arc<dyn Matchable>>, _remove: Option<Vec<Arc<dyn Matchable>>>, _terminators: Vec<Arc<dyn Matchable>>, _replace_terminators: bool, ) -> Arc<dyn Matchable>

impl PartialEq for Nothing

fn eq(&self, other: &Nothing) -> 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.
