Struct rustc_ap_rustc_span::def_id::DefId

pub struct DefId {
    pub krate: CrateNum,
    pub index: DefIndex,
}

A DefId identifies a particular definition, by combining a crate index and a def index.

You can create a DefId from a LocalDefId using local_def_id.to_def_id().

Fields

krate: CrateNum

index: DefIndex

Implementations

impl DefId

pub fn local(index: DefIndex) -> DefId

Makes a local DefId from the given DefIndex.

pub fn is_local(self) -> bool

Returns whether the item is defined in the crate currently being compiled.

pub fn as_local(self) -> Option<LocalDefId>

pub fn expect_local(self) -> LocalDefId

pub fn is_top_level_module(self) -> bool
