Enum SettingDifference 

#[non_exhaustive]
pub enum SettingDifference {
    #[non_exhaustive]
    SettingChanged {
        setting: String,
    },
    #[non_exhaustive]
    SettingUnrecorded {
        setting: String,
    },
}

How a setting that can produce a diagnostic’s change compares across the two reports. A diagnostic carrying one may not reflect a change in the data.

Two settings are read: columns, the column selection, on an added or removed column, and identifier_columns on a type change to or from identifier, the one type a setting assigns. An input path that types the same data differently is not recorded, so it cannot be named here (#906).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

#[non_exhaustive]

SettingChanged

The setting differs between the two reports for this column.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

setting: String

The configuration field that differs.

#[non_exhaustive]

SettingUnrecorded

At least one side did not record the setting, so it cannot be shown to be the same.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

setting: String

The configuration field that is unrecorded.
