Struct fog_pack::validator::MultiValidator

pub struct MultiValidator(pub Vec<Validator>);

“Multi” validator that checks with several validators at once.

This validator will accept any value that passes at least one of its contained validators. This can be used like an “any of” operator, or a logical OR of validators.

When going through the contained validators, some rules are followed to avoid possible cyclic references:

• Contained Multi-validators are skipped
• Contained Ref validators that refer to a Multi-validator are skipped.
• Contained Ref validators that refer to a Ref validator are skipped.

More succintly, the banned sequences are: Multi->Multi, Multi->Ref->Multi, Multi->Ref->Ref.

Query Checking

The validator for a query must be accepted by at least one of the validators in the Multi-validator. Contained validators that violate the cyclic reference rules are skipped (see above).
