Enum JsonLdExpansionPolicy 

pub enum JsonLdExpansionPolicy {
    Relaxed,
    Standard,
    Strict,
    Strictest,
}

Key expansion policy.

The default behavior of the expansion algorithm is to drop keys that are not defined in the context unless:

• there is a vocabulary mapping (@vocab) defined in the context; or
• the term contains a : character.

In other words, a key that cannot be expanded into an IRI or a blank node identifier is dropped unless it contains a : character.

Sometimes, it is preferable to keep undefined keys in the expanded document, or to forbid them completely by raising an error. You can define your preferred policy using one of this type variant with the JsonLdExpansionOptions::policy field.

Variants

Relaxed

Relaxed policy.

Undefined keys are always kept in the expanded document using the JsonLdLenient::Invalid variant.

Standard

Standard policy.

Every key that cannot be expanded into an IRI or a blank node identifier is dropped unless it contains a : character.

Strict

Strict policy.

Every key that cannot be expanded into an IRI or a blank node identifier will raise an error unless the term contains a : character.

Strictest

Strictest policy.

Every key that cannot be expanded into an IRI or a blank node identifier will raise an error.
