Trait Implementations

impl Clone for Diagnostic

fn clone(&self) -> Diagnostic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Diagnostic

Formats the value using the given formatter.

impl Extend<Diagnostic> for Diagnostics

fn extend<T: IntoIterator<Item = Diagnostic>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

impl From<Diagnostic> for Diagnostics

fn from(diagnostics: Diagnostic) -> Self

Converts to this type from the input type.

impl FromIterator<Diagnostic> for Diagnostics

fn from_iter<T: IntoIterator<Item = Diagnostic>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for Diagnostic

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 for Diagnostic

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

Tests for self and other values to be equal, and is used by ==.

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

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