Struct DocFragment

    pub span: Span,

Expand description

A portion of documentation, extracted from a #[doc] attribute.

Each variant contains the line number within the complete doc-comment where the fragment starts, as well as the Span where the corresponding doc comment or attribute is located.

Included files are kept separate from inline doc comments so that proper line-number information can be given when a doctest fails. Sugared doc comments and “raw” doc comments are kept separate because of issue #42760.

Fields§

§span: Span§item_id: Option<DefId>

The item this doc-comment came from. Used to determine the scope in which doc links in this fragment are resolved. Typically filled for reexport docs when they are merged into the docs of the original reexported item. If the id is not filled, which happens for the original reexported item, then it has to be taken from somewhere else during doc link resolution.

§doc: Symbol§kind: DocFragmentKind§indent: usize§from_expansion: bool

Because we tamper with the spans context, this information cannot be correctly retrieved later on. So instead, we compute it and store it here.
