Trait wagon_utils::ResultPeek

pub trait ResultPeek<T, E>: Peek + Iterator<Item = Result<T, E>> {
    // Required method
    fn peek_result(&mut self) -> Result<&T, E>;
}

Same as ResultNext but for things that implement Peek.

This trait is automatically implemented for any iterator of Results that has an error type E such that &E: From<UnexpectedEnd>.

Required Methods

fn peek_result(&mut self) -> Result<&T, E>

See next_result.

Errors

Should return Err if the underlying item is an Err, or there are no more items in the iterator.

Object Safety

This trait is not object safe.

Implementors
