Implementations§

source§

impl ExpnHash

source

pub fn stable_crate_id(self) -> StableCrateId

Returns the StableCrateId identifying the crate this ExpnHash originates from.

source

pub fn local_hash(self) -> u64

Returns the crate-local part of the ExpnHash.

Used for tests.

source

pub fn is_root(self) -> bool

source

fn new(stable_crate_id: StableCrateId, local_hash: u64) -> ExpnHash

Builds a new ExpnHash with the given StableCrateId and local_hash, where local_hash must be unique within its crate.
