Standardized Component.name values.

The schema types Component.name as a plain string, since a Charging Station may expose vendor-specific components alongside these.

An open set: values the specification doesn’t define are carried in Self::Other rather than rejected, so a deployment’s own values survive a deserialize/serialize round trip.

Comparison and hashing go through the wire string, not the variant, so Other("...") holding a standardized value compares equal to that variant.

May support momentary inputs (‘Operated’) or modal state (‘Active’). Multiple input sources should use explicit Variable instance keys (where the input function is key name).

Other(String<50usize>)

A value this version’s specification doesn’t define – typically a vendor-specific one, which OCPP explicitly permits.

Bounded at 50 bytes, the same maxLength the wire field carries, so anything the field can hold this can hold. Prefer Self::from_wire_or_other over constructing this directly: it returns the standardized variant when the value is one, keeping a single representation per wire string.

Implementations

impl ComponentName
