chaynabors opened PR #12950 from chaynabors:add-wasi-http-c-api to bytecodealliance:main:

Closes #12943

Adds wasi:http support to the C API following the same pattern as wasip2. The wasi-http feature implies wasi and is enabled by default.

New C API functions:

• wasmtime_component_linker_add_wasi_http
• wasmtime_context_set_wasi_http

It would be possible to construct WasiHttpCtx::new() directly, but I kept it optional and enabled consumers of the API to pass their own in the event that the WasiHttpCtx type becomes more configurable. Something that I think would be pretty reasonable.
