this is a thin wrapper around the desired Go API to give us types closer to Rust FFI.

ToStdError will convert the given error to an StdError.

ToSystemError will try to convert the given error to a SystemError.

These are the only two valid values for IbcOrder.

This is a 2-level result.

QueryRequest is an rust enum and only (exactly) one of the fields should be set Should we do a cleaner approach in Go? (type/data?).

RawQuery response is raw bytes ([]byte).

DelegationResponse is the expected response to DelegationsQuery.

SmartQuery response is raw bytes ([]byte).

StargateQuery is encoded the same way as abci_query, with path and protobuf encoded request data.

CanonicalAddress uses standard base64 encoding, just use it as a label for developers.

Coins handles properly serializing empty amounts.

HumanAddress is a printable (typically bech32 encoded) address string.

IBCChannels must JSON encode empty array as [] (not null) for consistency with Rust parser.

IBCEndpoints must JSON encode empty array as [] (not null) for consistency with Rust parser.
