Struct Warnings 

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

Set of Warnings.

Implementations

impl Warnings

pub fn is_empty(&self) -> bool

Checks if there’s at least one warning.

pub fn len(&self) -> usize

Returns the number of contained warnings.

pub fn iter(&self) -> impl ExactSizeIterator<Item = &Warning> + '_

Iterates over the contained warnings in no particular order.

pub fn into_result(self) -> Result<(), Self>

Converts these warnings into a Result. This is useful to treat warnings as errors.

Errors

Returns Err(_) if there’s at least one warning.

Trait Implementations

impl Debug for Warnings

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

Formats the value using the given formatter.

impl Display for Warnings

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

Formats the value using the given formatter.

impl Error for Warnings

Available on crate feature std only.

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 IntoIterator for Warnings

type Item = Warning

The type of the elements being iterated over.

type IntoIter = IntoIter<Warning>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
