Struct Diagnostics 

pub struct Diagnostics(/* private fields */);

A collection of diagnostics, returned whole rather than one at a time.

Implementations

impl Diagnostics

pub fn new() -> Self

pub fn push(&mut self, d: Diagnostic)

pub fn extend(&mut self, other: Diagnostics)

pub fn iter(&self) -> impl Iterator<Item = &Diagnostic>

pub fn errors(&self) -> impl Iterator<Item = &Diagnostic>

pub fn has_errors(&self) -> bool

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn into_errors(self) -> Vec<Diagnostic>

Drops warnings and notes, keeping only errors.

Trait Implementations

impl Clone for Diagnostics

fn clone(&self) -> Diagnostics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Diagnostics

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

Formats the value using the given formatter.

impl Default for Diagnostics

fn default() -> Diagnostics

Returns the “default value” for a type.

impl Display for Diagnostics

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

Formats the value using the given formatter.

impl Eq for Diagnostics

impl Error for Diagnostics

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl FromIterator<Diagnostic> for Diagnostics

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

Creates a value from an iterator.

impl IntoIterator for Diagnostics

type Item = Diagnostic

The type of the elements being iterated over.

type IntoIter = IntoIter<Diagnostic>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Diagnostics

fn eq(&self, other: &Diagnostics) -> 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.
