Get events by event key

Event key is a global index for an event stream.

It is hex-encoded BCS bytes of EventHandle guid field value, which is a combination of a uint64 creation number and account address (without trimming leading zeros).

For example, event key 0x00000000000000000000000000000000000000000a550c18 is combined by the following 2 parts:

1. 0000000000000000: uint64 representation of 0.
2. 0000000000000000000000000a550c18: 16 bytes of account address.

Event sequence_number is unique id of an event in an event stream. Event sequence_number starts from 0 for each event key.

String representation of an on-chain Move type tag that is exposed in transaction payload.

Values:

• bool
• u8
• u64
• u128
• address
• signer
• vector: vector<{non-reference MoveTypeId}>
• struct: {address}::{module_name}::{struct_name}::<{generic types}>

Vector type value examples:

• vector<u8>
• vector<vector<u64>>
• vector<0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>>

Struct type value examples:

• `0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>
• 0x1::account::Account

Note:

1. Empty chars should be ignored when comparing 2 struct tag ids.
2. When used in an URL path, should be encoded by url-encoding (AKA percent-encoding).

Move bool type value is serialized into boolean.

Move u8 type value is serialized into integer.

Move u64 and u128 type value is serialized into string.

Move address type value(16 bytes Aptos account address) is serialized into hex-encoded string, which is prefixed with 0x and leading zeros are trimmed.

For example:

• 0x1
• 0x1668f6be25668c1a17cd8caf6b8d2f25

Move vector type value is serialized into array, except vector<u8> which is serialized into hex-encoded string with 0x prefix.

For example:

• vector<u64>{255, 255} => ["255", "255"]
• vector<u8>{255, 255} => 0xffff

Move struct type value is serialized into object that looks like this (except some Move stdlib types, see the following section):

{
  field1_name: field1_value,
  field2_name: field2_value,
  ......
}

For example: { "created": "0xa550c18", "role_id": "0" }

Special serialization for Move stdlib types:

• 0x1::string::String is serialized into string. For example, struct value 0x1::string::String{bytes: b"hello world"} is serialized as "hello world" in JSON.
