Wrapper types to enable optimized handling of
unidiomatic way to derive default trait implementations of TryFrom in/out of SerializedBytes
A simple macro to wrap return_err_ptr in an analogy to the native rust
A Canonical Serialized Bytes representation for data If you have a data structure that needs a canonical byte representation use this Always round-trip through SerializedBytes via. a single TryFrom implementation. This ensures that the internal bytes of SerializedBytes are indeed canonical. The corrolary is that if bytes are NOT wrapped in SerializedBytes we can assume they are NOT canonical. Typically we need a canonical middleware when data is to be handled at the byte level by independently implemented and maintained systems.
UnsafeBytes the only way to implement a custom round trip through bytes for SerializedBytes It is intended to be an internal implementation in TryFrom implementations The assumption is that any code using UnsafeBytes is NOT valid messagepack data This allows us to enforce that all data round-tripping through SerializedBytes is via TryFrom and also allow for custom non-messagepack canonical representations of data types.
Enum of all possible ERROR codes that a Zome API Function could return.
A data structure that can be deserialized from any data format supported by Serde.
A data structure that can be serialized into any data format supported by Serde.
Simple and safe type conversions that may fail in a controlled
way under some circumstances. It is the reciprocal of
An attempted conversion that consumes
Receive arguments from the host.
The guest sets the type O that the host needs to match.
If deserialization fails then a
Convert an Into
Convert any serializable value into a GuestPtr that can be returned to the host. The host is expected to know how to consume and deserialize it.
a WasmSize integer that points to a position in wasm linear memory that the host and guest are sharing to communicate across function calls
a WasmSize integer that represents the size of bytes to read/write to memory in direct manipulations
something like usize for wasm wasm has a memory limit of 4GB so offsets and lengths fit in u32
