Trait embedded_io::Io

pub trait Io {
    type Error: Error;
}
Expand description

Base trait for all IO traits.

All IO operations of all traits return the error defined in this trait.

Having a shared trait instead of having every trait define its own io::Error enforces all impls on the same type use the same error. This is very convenient when writing generic code, it means you have to handle a single error type T::Error, instead of <T as Read>::Error, <T as Write>::Error which might be different types.

Required Associated Types

Error type of all the IO operations on this type.
