Struct rustc_typeck::check_unused::ExternCrateToLint[−][src]

struct ExternCrateToLint {
    def_id: DefId,
    span: Span,
    orig_name: Option<Symbol>,
    warn_if_unused: bool,
}

Fields

def_id: DefId
Expand description

DefId of the extern crate

span: Span
Expand description

span from the item

orig_name: Option<Symbol>
Expand description

if Some, then this is renamed (extern crate orig_name as crate_name), and – perhaps surprisingly – this stores the original name (item.name will contain the new name)

warn_if_unused: bool
Expand description

if false, the original name started with _, so we shouldn’t lint about it going unused (but we should still emit idiom lints).
