Struct ErrorCollector

pub struct ErrorCollector<E> { /* private fields */ }

A collection of errors that can be accumulated and returned as a single result

Implementations

impl<E> ErrorCollector<E>

pub fn new() -> Self

Create a new empty error collector

pub fn push(&mut self, error: E)

Add an error to the collection

pub fn with(self, error: E) -> Self

Add an error to the collection and return self for chaining

pub fn is_empty(&self) -> bool

Check if the collection is empty

pub fn len(&self) -> usize

Get the number of collected errors

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

Return a result that is Ok if there are no errors, or Err with the collector otherwise

pub fn result<T>(&self, ok_value: T) -> Result<T, &Self>

Return a result that is Ok if there are no errors, or Err with the collector otherwise

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

Consume the collector and return the vector of errors

pub fn errors(&self) -> &Vec<E>

Get a reference to the vector of errors

pub fn errors_mut(&mut self) -> &mut Vec<E>

Get a mutable reference to the vector of errors

pub fn extend(&mut self, other: ErrorCollector<E>)

Add all errors from another collector

pub fn try_collect<F, T>(&mut self, op: F) -> Option<T>

where F: FnOnce() -> Result<T, E>,

Try an operation that may return an error, collecting the error if it occurs

impl<E: ForgeError> ErrorCollector<E>

pub fn summary(&self) -> String

Return a summary of the collected errors using ForgeError traits

pub fn has_fatal(&self) -> bool

Check if any of the collected errors is marked as fatal

pub fn all_retryable(&self) -> bool

Check if all collected errors are retryable

Trait Implementations

impl<E: Debug> Debug for ErrorCollector<E>

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

Formats the value using the given formatter.

impl<E: Default> Default for ErrorCollector<E>

fn default() -> ErrorCollector<E>

Returns the “default value” for a type.

impl<E: Display> Display for ErrorCollector<E>

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

Formats the value using the given formatter.

impl<E: Error> Error for ErrorCollector<E>

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.
