Implementations

impl<'db> ProjectionStore<'db>

pub fn shrink_to_fit(&mut self)

pub fn intern_if_exist( &self, projection: &[ProjectionElem<'db, Idx<Local<'db>>>], ) -> Option<ProjectionId>

pub fn intern( &mut self, projection: Box<[ProjectionElem<'db, Idx<Local<'db>>>]>, ) -> ProjectionId

Trait Implementations

impl<'db> Clone for ProjectionStore<'db>

fn clone(&self) -> ProjectionStore<'db>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for ProjectionStore<'db>

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

Formats the value using the given formatter.

impl Default for ProjectionStore<'_>

fn default() -> ProjectionStore<'_>

Returns the “default value” for a type.

impl<'db> PartialEq for ProjectionStore<'db>

fn eq(&self, other: &ProjectionStore<'db>) -> 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.
