Struct Diagnostic 

#[non_exhaustive]
pub struct Diagnostic {
    pub code: DiagnosticCode,
    pub column: String,
    pub data_type: Option<Sides<DataType>>,
    pub setting: Option<SettingDifference>,
    pub message: String,
}

A schema change between the baseline and the report.

A warning, not a fourth verdict: it is reported whatever the policy states, and no rule decides on it. A requirement that would fail on it is a policy entry of its own.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

code: DiagnosticCode

What changed.

column: String

The column it changed in.

data_type: Option<Sides<DataType>>

The inferred type on each side, a being the baseline. Present on DiagnosticCode::ColumnTypeChanged only.

setting: Option<SettingDifference>

A recorded setting that can produce the change on unchanged data, when one can. Serialized flat, as a check’s reason is.

message: String

A fixed sentence naming the change, free of numbers and names, like a check’s message.
