Trait ErrorCollector 

pub trait ErrorCollector<E> {
    type Collection;

    // Required methods
    fn empty() -> Self;
    fn push_err(&mut self, err: E) -> ControlFlow;
    fn with_value<T>(self, val: T) -> Result<T, Self::Collection>;
}

Determines the manner in which the encountered error(s) are processed, stored and returned, as well as whether the iteration should continue or not.

Required Associated Types

type Collection

The type to be returned after the iteration has been stopped

Required Methods

fn empty() -> Self

Creates an empty ErrorCollector.

fn push_err(&mut self, err: E) -> ControlFlow

Processes an error. Returns an ControlFlow type indicating whether the iteration shall stop or not.

fn with_value<T>(self, val: T) -> Result<T, Self::Collection>

Returns Ok(val) if the iteration run to completion, or an error collection of type Self::Collection if error(s) were encountered.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
