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.

Always

Pull the image before every service start.

Never

Never pull and rely on a cached image.

Missing

Pull only when the image is missing.

IfNotPresentAlias

The retained if_not_present alias for Self::Missing.

Build

Build the image before starting the service.

Daily

Check for an updated image once per day.

Weekly

Check for an updated image once per week.

Every

Check after the retained custom Compose duration.

Fields

duration: String

Duration spelling after the every_ prefix.

RefreshSchemaOnly

The schema-recognized refresh spelling, which lacks matching service-field documentation.

Expression

A policy that still contains a Compose interpolation expression.

Other

An invalid or provider-specific value retained for diagnostics.
