Struct RenderContext 

pub(crate) struct RenderContext<'a, 'db> {
    completion: &'a CompletionContext<'a, 'db>,
    is_private_editable: bool,
    import_to_add: Option<LocatedImport>,
    doc_aliases: Vec<SmolStr>,
}

Interface for data and methods required for items rendering.

Fields

completion: &'a CompletionContext<'a, 'db>

is_private_editable: bool

import_to_add: Option<LocatedImport>

doc_aliases: Vec<SmolStr>

Implementations

impl<'a, 'db> RenderContext<'a, 'db>

pub(crate) fn new( completion: &'a CompletionContext<'a, 'db>, ) -> RenderContext<'a, 'db>

pub(crate) fn private_editable(self, private_editable: bool) -> Self

pub(crate) fn import_to_add(self, import_to_add: Option<LocatedImport>) -> Self

pub(crate) fn doc_aliases(self, doc_aliases: Vec<SmolStr>) -> Self

fn snippet_cap(&self) -> Option<SnippetCap>

fn db(&self) -> &'a RootDatabase

fn source_range(&self) -> TextRange

fn completion_relevance(&self) -> CompletionRelevance

fn is_immediately_after_macro_bang(&self) -> bool

fn is_deprecated( &self, def: impl HasAttrs, def_as_assoc_item: Option<AssocItem>, ) -> bool

Whether def is deprecated.

This can happen for two reasons:

• the def is marked with #[deprecated]
• the def is an assoc item whose trait is deprecated

In order to be able to check for the latter, we’d ideally want to try_as_dyn<_, dyn AsAssocItem>(def) (see try_as_dyn), but that function is currently unstable. Therefore, we employ a hack instead: if def can be an assoc item, it should be passed to this method as follows:

self.is_deprecated(def, Some(def))

otherwise, it should be passed as:

self.is_deprecated(def, None)

fn is_variant_deprecated(&self, variant: EnumVariant) -> bool

Whether an enum variant should be rendered as deprecated.

A variant inherits deprecation from its parent enum, matching rustc’s behavior where #[deprecated] on an enum applies to its variants.

fn docs(&self, def: impl HasDocs) -> Option<Documentation<'a>>
