Trait ErrorType 

pub trait ErrorType {
    type Error: Error;
}

Base trait for all IO traits, defining the error type.

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 Error associated type 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 and <T as Write>::Error which might be different types.

Required Associated Types

type Error: Error

Error type of all the IO operations on this type.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
