Trait ErrorCollector 

pub trait ErrorCollector<E> {
    type WrappedInner;

    // Required methods
    fn push_error(&mut self, error: E);
    fn propagate(self, other: &mut impl ErrorCollector<E>) -> Self::WrappedInner;
}

Something which tracks a collection of errors.

This generalizes methods like ErrorSentinel::propagate which allow errors to be handled by merging them into a different collection of errors.

Required Associated Types

type WrappedInner

The type returned by propagate.

Required Methods

fn push_error(&mut self, error: E)

Add a new error to the collection of errors.

fn propagate(self, other: &mut impl ErrorCollector<E>) -> Self::WrappedInner

Consumes this collector and pushes all of its errors into a different collector. If the type is wrapping some kind of value, it may return it too.

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.
