Struct flex_error::NoSource[−][src]

pub struct NoSource;
Expand description

An ErrorSource that can be used to represent to lack of any error source. Both its Source and Detail types are (). This can be used for primitive errors that are not caused by any error source.

In practice, it is also possible to omit specifying any error source inside define_error!, which has similar effect as using NoSource but with the source field omitted entirely.
