Implementations§
source§impl ExpnHash
impl ExpnHash
sourcepub fn stable_crate_id(self) -> StableCrateId
pub fn stable_crate_id(self) -> StableCrateId
Returns the StableCrateId identifying the crate this ExpnHash originates from.
sourcepub fn local_hash(self) -> Hash64
pub fn local_hash(self) -> Hash64
Returns the crate-local part of the ExpnHash.
Used for assertions.
pub fn is_root(self) -> bool
sourcefn new(stable_crate_id: StableCrateId, local_hash: Hash64) -> ExpnHash
fn new(stable_crate_id: StableCrateId, local_hash: Hash64) -> ExpnHash
Builds a new ExpnHash with the given StableCrateId and
local_hash
, where local_hash
must be unique within its crate.
