Struct BuildErrors 

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

A collection of BuildErrors from a failed build pipeline.

Wraps a Vec<BuildError> and provides emit_cargo_errors() for printing each error as a cargo::error= directive.

Implementations

impl BuildErrors

pub fn errors(&self) -> &[BuildError]

Return a borrowed slice of the contained errors.

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

Consume this collection and return the inner Vec<BuildError>.

pub fn is_empty(&self) -> bool

Returns true if there are no errors.

pub fn len(&self) -> usize

Returns the number of errors.

pub fn emit_cargo_errors(&self)

Print each error as a cargo::error= directive to stdout.

Trait Implementations

impl Clone for BuildErrors

fn clone(&self) -> BuildErrors

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuildErrors

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

Formats the value using the given formatter.

impl Display for BuildErrors

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

Formats the value using the given formatter.

impl Error for BuildErrors

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.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for BuildErrors

type Item = BuildError

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
