WasmEdgeV2 is V2 of the WasmEdge sockets extension to WASI preview 1.

Version 2 has a sock_accept function that's compatible with the WASI preview 1 specification. It widens addresses so that additional address families could be supported in future (e.g. AF_UNIX).

Functions

func NewHostModule 

func NewHostModule(extensions ...Extension) wazergo.HostModule[*Module]

NewHostModule constructs a wazero host module for WASI.

The host module manages the interaction between the host and the guest WASM module. The host module does not implement WASI on its own, and instead calls out to an implementation of the wasi.System interface provided via the WithWASI host module Option. This design means that the implementation doesn't have to concern itself with ABI details nor access the guest's memory.
