Enum rustc_resolve::CrateLint

pub(crate) enum CrateLint {
    No,
    SimplePath(NodeId),
    UsePath {
        root_id: NodeId,
        root_span: Span,
    },
    QPathTrait {

    },
}

Variants

No

Do not issue the lint.

SimplePath(NodeId)

This lint applies to some arbitrary path; e.g., impl ::foo::Bar. In this case, we can take the span of that path.

UsePath

Fields

root_id: NodeId

root_span: Span

This lint comes from a use statement. In this case, what we care about really is the root use statement; e.g., if we have nested things like use a::{b, c}, we care about the use a part.

QPathTrait

Fields

qpath_id: NodeId

qpath_span: Span

This is the “trait item” from a fully qualified path. For example, we might be resolving X::Y::Z from a path like <T as X::Y>::Z. The path_span is the span of the to the trait itself (X::Y).

Implementations

impl CrateLint

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
