macro_rules! parse_error_type {
    ($vis:vis $name:ident, $source:ty, $subject:expr $(, $derive:path)* $(,)?) => { ... };

The resulting type is public, conditionally implements std::error::Error and has a private new() method for convenience.

Parameters

• name - the name of the error type
• source - the type of the source type
• subject - English description of the type being parsed (e.g. “a bitcoin amount”)
• derive - list of derives to add
