Struct rustc::lint::Context[src]

pub struct Context<'a> {
    pub tcx: &'a ctxt,
    pub krate: &'a Crate,
    pub exported_items: &'a ExportedItems,
    // some fields omitted
}

Context for lint checking.

Fields

tcx

Type context we're checking in.

krate

The crate being checked.

exported_items

Items exported from the crate being checked.

Methods

impl<'a> Context<'a>

fn sess(&'a self) -> &'a Session

Get the overall compiler Session object.

fn lint(&self, lint: &'static Lint, msg: &str)

Emit a lint at the appropriate level, with no associated span.

fn span_lint(&self, lint: &'static Lint, span: Span, msg: &str)

Emit a lint at the appropriate level, for a particular span.
