AbiEvent

An event emitted by a contract response.

AbiResponse

CBOR-native representation of a cosmwasm execute/instantiate/external_event Response. Only carries the fields the host actually needs; skips messages and sub-messages.

AbiResultPayload

The inner payload returned by every ABI handler, CBOR-encoded inside HostAbiResponse.payload.

HostAbiError

Error object returned by the host ABI envelope.

HostAbiResponse

Top-level response envelope used by host ABI exports.

Constants

ERR_HANDLER_PANIC

ERR_INVALID_CBOR

ERR_INVALID_POINTER

ERR_SERIALIZATION_FAILED

HOST_ABI_MANIFEST_FIELD

HOST_ABI_VERSION

HOST_ABI_WIRE_FORMAT

HOST_ABI_WIRE_FORMAT_MANIFEST_FIELD

Functions

alloc

Allocates len bytes in wasm linear memory and returns pointer.

cbor_from_slice

Deserialize CBOR bytes into a value.

cbor_to_vec

Serialize a value to CBOR bytes.

dispatch

Reads input bytes, invokes a handler, and returns an encoded ABI response.

dispatch_response

Converts handler output (or failure) into HostAbiResponse.

encode_response

Serializes HostAbiResponse to CBOR and writes it into wasm memory.

free^⚠

Frees memory previously allocated via alloc.

pack_ptr_len

Packs (ptr, len) into a single u64 where the high 32 bits hold length.

read_memory

Reads a byte slice from wasm linear memory.

unpack_ptr_len

Unpacks a pointer/length pair produced by pack_ptr_len.

write_memory

Writes bytes into wasm linear memory and returns a packed pointer/length pair.
