Struct IoError

Source
pub struct IoError(/* private fields */);
Expand description

A version of std::io::Error implemented on top of Arc instead of Box, making it cloneable.

The API of this type has been designed to match io::Error, with two exceptions:

See the standard library documentation for more detailed API-level descriptions than are given here.

IoError implements From for io::Error and vice-versa, so the two types can easily be converted between each other. A type containing io::Error can be made Clone-compatible by instead storing IoError internally and converting from/to io::Error on API boundaries.

Clones derived from the same original IoError instance will share a single heap-allocated error instance (if one is present) using Arc. io::Error instances produced by converting those clones back with the From implementation will also share the same single error instance.
