Module native 

Optional typed IC entrypoints using Platform’s export generator and executor. Explicit resource admission for native Serde payloads in the same Postcard format.

Types, IDs, deterministic serialization and domain rules are consumer-owned. Resource admission follows Serde visits; no static schema is inferred. Custom Serde implementations are trusted: allocations/work outside visited values cannot be constrained here. See the runtime guide for budget semantics.

Constants

REQUEST_HEADER_BYTES

Native request frame header size, including magic, identity and direction.

Functions

decode

Decode a complete Postcard payload; allocation admission precedes visitor calls. Borrowed bytes and strings may refer directly to the input for its lifetime. Primitive representations are checked while reading; Serde normalization is consumer-owned.

decode_request

Check request identity and direction before decoding its bounded native value.

decode_response

Check response identity and direction before decoding its bounded native value.

encode

Encode an owned or borrowed native payload under explicit traversal allowances.

encode_into

Encode into reusable caller storage. Previous contents are cleared, including on error. Capacity may be lost on serialization failure; successful calls retain it. Retain a separate immutable frame when bytes must survive subsequent calls for retries.

encode_request

Encode a complete request; limits.bytes includes the canonical frame header.

encode_request_into

Encode a request into reusable storage; follows encode_into failure semantics.

encode_request_to_slice

Encode a complete request into caller storage; follows encode_to_slice.

encode_response

Encode a complete response, including borrowed response projections.

encode_response_into

Encode a response into reusable storage; follows encode_into failure semantics.

encode_response_to_slice

Encode a complete response into caller storage; follows encode_to_slice.

encode_to_slice

Encode a payload into caller-owned storage without allocating codec output.

encoded_frame_len

Measure a request or response frame; both directions have equal header length.

encoded_len

Measure one native payload with no output allocation; bytes excludes a frame.

method_id

Stable automatic endpoint identity from the exact exported IC method name.

validate_request_header

Validate only the fixed request header before a transport copies the payload. The complete request still requires normal decoding and resource admission. This delegates to the same validator previously used inside Wire’s endpoint module: accepted bytes and error ordering are unchanged after its package move.

with_encoded

Encode a payload using scratch storage or owned fallback, then consume its bytes.
