Crate flexible_io

Flexible IO allows you to choose seekable or buffered IO at runtime.

The motivation of this is enabling APIs in which use of a reader (or writer) can be optimized in case of it being buffered, but it’s not required for correct functioning. Or, an API where the Seek requirement is only determined at runtime, such as when a portion of the functionality does not depend on it, and an error should be returned.

Note that the wrapped type can not be unsized (dyn trait) itself. This may be fixed at a later point to make the reader suitable for use in embedded. In particular, the double indirection of instantiating with R = &mut dyn Read wouldn’t make sense as the setters would not be usable, their bounds can never be met. And combining traits into a large dyn-trait is redundant as it trait-impls become part of the static validity requirement again.
