2023-10-17examples/rust: Do some simplification around unsafe {} blocksAndrew Clayton1-12/+8
We can put the unsafe keyword as part of the function definition, getting rid of the unsafe {} blocks in the functions themselves. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-09-25examples/rust: Amend upload-reflector for recent changesAndrew Clayton1-1/+2
The previous commit changed uwr_get_http_content_len() to return a u64 to allow for uploads larger than 4GiB, which now means this generates compiler errors about type mismatches, expected usize got u64. Cast the return value of uwr_get_http_content_len() to usize to match that of TOTAL_RESPONSE_SENT. (Making TOTAL_RESPONSE_SENT a u64 creates a larger trail of problems).

2023-08-30examples/rust: Update for new API additionsAndrew Clayton1-1/+1
Update the echo-request and upload-reflector examples for the new uwr_http_add_header_content_type() and uwr_http_add_header_content_len() functions. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-28libunit-wasm: Remove the idx argument from luw_http_add_header()Andrew Clayton1-2/+1
This was used to specify the index of the response header being added, starting at 0 and incrementing by one for each header. Instead of having the programmer specify this, track it internally. We add an extra check in luw_http_add_header() to make sure we aren't trying to add more headers than we said with luw_http_init_headers(), if we are, simply return. This updates the API-C.md and the various examples and 'rusty' API wrapper. Suggested-by: Liam Crilly <liam@nginx.com> Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-25Rust: Port the Rust Wasm demos to the new 'rusty' wrappersAndrew Clayton1-85/+58
rusty is a thin wrapper over the generated libunit-wasm bindings to provide a more native rust like interface. This gets rid of all the casting and ugly string handling. It massively reduces the amount of unsafe {} blocks needed, though some still are... All in all this provides a nice code cleanup. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
