Module candid::types

Provides Candid type conversion and serialization.

• CandidType trait converts a Rust type to Candid type types::Type. The implementation for user-defined data types can be derived from candid_derive crate.
• Serializer trait serializes a Rust value to Candid binary format. We do not use Serde’s Serialize trait because Candid requires serializing types along with the values. This is difficult to achieve in Serialize, especially for enum types.
