Struct ra_ap_hir_ty::ProjectionTy

pub struct ProjectionTy {
    pub associated_ty_id: AssocTypeId,
    pub substitution: Substitution,
}

A “projection” type corresponds to an (unnormalized) projection like <P0 as Trait<P1..Pn>>::Foo. Note that the trait and all its parameters are fully known.

Fields

associated_ty_id: AssocTypeId

substitution: Substitution

Trait Implementations

impl Clone for ProjectionTy

fn clone(&self) -> ProjectionTy

Returns a copy of the value.

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

impl HirDisplay for ProjectionTy

fn hir_fmt(&self, f: &mut HirFormatter<'_>) -> Result<(), HirDisplayError>

fn into_displayable<'a>(
    &'a self,
    db: &'a dyn HirDatabase,
    max_size: Option<usize>,
    omit_verbose_types: bool,
    display_target: DisplayTarget
) -> HirDisplayWrapper<'a, Self> where
    Self: Sized, 

Returns a Displayable type that is human-readable.

fn display<'a>(&'a self, db: &'a dyn HirDatabase) -> HirDisplayWrapper<'a, Self> where
    Self: Sized, 

Returns a Displayable type that is human-readable. Use this for showing types to the user (e.g. diagnostics)

fn display_source_code<'a>(
    &'a self,
    db: &'a dyn HirDatabase,
    module_id: ModuleId
) -> Result<String, DisplaySourceCodeError>

Returns a String representation of self that can be inserted into the given module. Use this when generating code (e.g. assists)

fn display_test<'a>(
    &'a self,
    db: &'a dyn HirDatabase
) -> HirDisplayWrapper<'a, Self> where
    Self: Sized, 

Returns a String representation of self for test purposes

impl PartialEq<ProjectionTy> for ProjectionTy

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

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

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

This method tests for !=.
