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

Unstable (rustc_private)

Derived Implementations

impl Copy for DefId

impl Hash for DefId

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

impl Decodable for DefId

fn decode<__D: Decoder>(__arg_0: &mut __D) -> Result<DefId, __D::Error>

impl Encodable for DefId

fn encode<__S: Encoder>(&self, __arg_0: &mut __S) -> Result<(), __S::Error>

impl PartialEq for DefId

fn eq(&self, __arg_0: &DefId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &DefId) -> bool

This method tests for !=.

impl PartialOrd for DefId

fn partial_cmp(&self, __arg_0: &DefId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &DefId) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &DefId) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &DefId) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &DefId) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Ord for DefId

fn cmp(&self, __arg_0: &DefId) -> Ordering

This method returns an Ordering between self and other.

impl Eq for DefId

impl Clone for DefId

fn clone(&self) -> DefId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
