Module param 

Parameters

A decoded parameter and the iCalendar parameter-name vocabulary.

IcalParam is a closed set of the parameters RFC 5545 and its extensions define, one variant each, plus an Unknown arm so anything else round-trips. Parameters are few and simple (a text or a small list), so unlike properties each variant carries its value directly rather than through a shared value type; the variant itself names the parameter. A known name is the closed IcalParamKind, reached through FromStr and Deref. Pure model, no crate::tree dependency.

Parse iCalendar parameter kind error.

Enums

IcalParam

A decoded parameter: one known kind, or Unknown for anything unmodelled. The list-valued parameters (DELEGATED-FROM, DELEGATED-TO, MEMBER, FEATURE) carry a vector; the rest carry a single value.

IcalParamKind

The closed iCalendar parameter-name vocabulary, one fieldless variant per known parameter. An identity for dispatch and allowed-sets; the open counterpart that carries the value (and unknown names) is IcalParam.
