Struct OpCompatVersions 

pub struct OpCompatVersions {
    major: u32,
    minor: u32,
    span: Span,
}

Fields

major: u32

Increased when we make a wholly-incompatible change

Bumping this will cause rejection of AOPTIONS by old d-d engines. Hopefully a newer d-d will able to cope with both.

minor: u32

Increased when we make a more subtle change

Current d-d versions will ignore this. Bumping it can be used to psas information from a newer capturing d-d to a newer template/driver d-d.

span: Span

Span for error reporting
