impl DepGraphSafe for DefId
[src]
A DefId
on its own doesn't give access to any particular state.
You must fetch the state from the various maps or generate
on-demand queries, all of which create reads.
impl Clone for DefId
[src]
fn clone(&self) -> DefId
Returns a copy of the value. Read more
fn clone_from(&mut self, source: &Self)
1.0.0
Performs copy-assignment from source
. Read more
impl Eq for DefId
[src]
impl Ord for DefId
[src]
fn cmp(&self, __arg_0: &DefId) -> Ordering
This method returns an Ordering
between self
and other
. Read more
impl PartialOrd for DefId
[src]
fn partial_cmp(&self, __arg_0: &DefId) -> Option<Ordering>
This method returns an ordering between self
and other
values if one exists. Read more
fn lt(&self, __arg_0: &DefId) -> bool

) and is used by the <
operator. Read more
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. Read more
fn gt(&self, __arg_0: &DefId) -> bool
This method tests greater than (for self
and other
) and is used by the >
operator. Read more
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. Read more
impl PartialEq for DefId
[src]
fn eq(&self, __arg_0: &DefId) -> bool
This method tests for self
and other
values to be equal, and is used by ==
. Read more
fn ne(&self, __arg_0: &DefId) -> bool
This method tests for !=
.
impl Encodable for DefId
[src]
fn encode<__S: Encoder>(&self, __arg_0: &mut __S) -> Result<(), __S::Error>

impl Hash for DefId
[src]
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
1.3.0
Feeds a slice of this type into the state provided.
