Enum RewriteKind 

#[non_exhaustive]
pub enum RewriteKind {
    Policy {
        v3: String,
        v4: Vec<(String, String)>,
    },
    Function {
        v3: String,
        v4: String,
    },
}

What a Rewrite changed: the v4 keys and values the reader wrote, so a host that migrates a stored definition applies them instead of parsing Display’s prose.

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.

Policy

A v3 policy flag, read as the v4 policy keys written in its place.

Fields

v3: String

The v3 spelling as authored, such as continue_on_error: true; display only.

v4: Vec<(String, String)>

The v4 keys written and their values, in the definition’s order.

Function

A v3 function name, read as v4’s: validate as validation.

Fields

v3: String

The v3 name.

v4: String

The v4 name.
