Implementations

impl IntercrateAmbiguityCause

pub fn add_intercrate_ambiguity_hint(&self, err: &mut Diagnostic)

Emits notes when the overlap is caused by complex intercrate ambiguities. See #23980 for details.

pub fn intercrate_ambiguity_hint(&self) -> String

Trait Implementations

impl Clone for IntercrateAmbiguityCause

fn clone(&self) -> IntercrateAmbiguityCause

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IntercrateAmbiguityCause

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for IntercrateAmbiguityCause

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl PartialEq<IntercrateAmbiguityCause> for IntercrateAmbiguityCause

fn eq(&self, other: &IntercrateAmbiguityCause) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
