23. Built-in containers 

• Option / Result / Map / Vec : basically we are interested in only inner values of the container

  Code Block
  language js
  { "core::option::Option<iroha_data_model::isi::Instruction>": { "Option": "iroha_data_model::isi::Instruction" }, "core::result::Result<i32, i32>": { "Result": { "ok": "i32", "err": "i32" } }, "alloc::collections::BTreeMap<alloc::string::String, i32>": { "Map": { "key": "alloc::string::String", "value": "i32" } }, "alloc::vec::Vec<i32>": { "Vec": "i32" } }

  
  

34. Custom containers 

• Named structures – structures which have field names
• Unnamed structures – structures with no field names (like zero sized structures in rust, or tuples, or struct WrappedTuple(i32, i32))
• Enums
  

  
  

  Code Block
  language js
  { "iroha_crypto::PublicKey": { "NamedStruct": { "declarations": [ { "name": "digest_function", "ty": "alloc::string::String" }, { "name": "payload", "ty": "alloc::vec::Vec<u8>" } ] } }, "iroha_data_model::account::SignatureCheckCondition": { "UnnamedStruct": { "types": [ "iroha_data_model::expression::EvaluatesTo<bool>" ] } }, "iroha_data_model::events::pipeline::EntityType": { "Enum": { "variants": [ { "name": "Block", "discriminant": 0, "ty": null }, { "name": "Transaction", "discriminant": 1, "ty": null } ] } }, }
