Struct add_ed::error::IOError

pub struct IOError {
    pub inner: Rc<dyn IOErrorTrait>,
}

A wrapper type for any IO implementation’s error type

To use the wrapper implement IOErrorTrait on the error type to wrap. The return types on the crate::IO trait’s methods will give automatic conversion via the ? operator in a lot of cases, but in some cases it is likely still needed to call .into() to convert.

Fields

inner: Rc<dyn IOErrorTrait>

Implementations

impl IOError

pub fn downcast_ref<T: IOErrorTrait>(&self) -> Option<&T>

Helper for downcasting into the internal error type

Due to how finnicky this is to get right, with coercing the Rc into &T before downcasting, I very much recommend using this helper.
