Struct internal_iterator::BreakValue

pub struct BreakValue<'a> { /* private fields */ }

Expand description

A helper type used in from_fn.

It represents a value that the iterator is stopped with, which from_fn closure needs to pass back to the caller. It has a lifetime parameter to prevent values from different scopes from getting mixed up (i.e. if from_fn is used within another from_fn).
