//! The wasm module holds serialization/encoding needed wasm bindings for
//! any types related to InviteKeyEnvelope. This means base64url for the
//! InviteKeyData type, and Bitwarden EncString text format (`"2.iv|data|mac"`)
//! for the InviteKeyEnvelope type. In order to minimize complexity, the actual
//! encoding/decoding is limited to the `From<String>` and `FromStr`
//! implementations. All other serialization goes through String to simplify
//! maintenance.
