Adivce on reducing code size in WASM target

[ruslantalpa]

According to rust/wasm docs, using generic functions can lead to a lot of bloat since the compiler creates copies of those functions.

I suspect that in my case, this is the reason why 140K in a .rs file for a parser generates about 600K of WASM bytecode.

Is there a possible solution for this (work around it by writing the parser functions differently)? It seems the most common "offenders" are choice between many combinators in my case since i use them extensively.

Thank you (and thank you for the lib, it was quite straightforward to port parser from parsec)

https://github.com/dtolnay/cargo-llvm-lines can be quite useful to track down where you end up with to many instantiations of some code but without an example of how your parser looks I can't really say anything specific.

In combine itself, it may be possible to move partial parsing behind a feature flag, allowing you to avoid including the code for it if it isn't necessary. It may be a bit complicated to implement though.

thank you for the reply, i'll try the tool you suggested,

I've used twiggy to get a sense of what's happening and the output looks like this

but this is when i build for for dev/with debug symbols, the release build does not have any info.

a typical parser function look like this

fn function_param<Input>() -> impl Parser<Input, Output = FunctionParam>
where
    Input: Stream<Token = char>,
{
    choice!(
        function_call().map(|(fn_name, parameters)| FunctionParam::Func {fn_name, parameters}),
        field().map(FunctionParam::Fld),
        between(
            char('\''), 
            char('\''), 
            many::<String,_,_>(none_of("'".chars())),
        )
        .and(optional(cast()))
        .map(|(v,c)| FunctionParam::Val(SingleVal(v,c.clone()),c))
    )
}

I am leaving the output above only for reference, no need to investigate deeper, I just reached out in case there is some "easy fix" that you are aware of (and would require no effort on your part besides a short comment).

Thank you again for the awesome lib and your time. I'll post back in case i discover something interesting in this area

[Marwes]

You could try using the choice function, instead of the choice! macro. At a guess, it may generate less code.

[Marwes]

Found a s small improvement for sequence parsers https://github.com/Marwes/combine/pull/351 .

I also hacked in a way to disable partial parsing via a feature flag in this branch https://github.com/Marwes/combine/tree/no_default_partial which you could try to see if and how much of a difference it makes. Can't say if it is a good idea to add, but knowing if it helps or not would be necessary first.

[klensy]

Interesting results, @ruslantalpa !

How you build crate for use with twiggy? I've tried to build it with wasm32-unknown-unknown and cdylib crate type, but it given error like error: function or code section is missing. If i build it with wasm32-wasi it shows only debug sections with other ones as mostly zero sized.

[ruslantalpa]

@Marwes thank you, i will try both your suggestions (though in about 1-2 weeks) and report back the results. thank you again for looking into this.

@klensy I basically setup the project like this the main part in Cargo.toml is basically

[lib]
crate-type = ["cdylib", "rlib"]

and i build it with wasm-pack build --target nodejs --dev and run twiggy with twiggy monos pkg/mylib_wasm_bg.wasm basically the setup/build was done through wasm-pack (not just cargo build)

[ruslantalpa]

@Marwes tried your new branch (though had to fork it and change the TRY_PARTIAL to pub to get it to compile)

results are: in release i see not big size difference (probably due to LLVM optimizations) but in dev mode there is definitely some improvement, a bit in size but also in the twiggy output, at a glance, the number of total monomorphizations per combinator is about half.

I will try to have a deeper understanding of what's going on, try things out and will report back as a reference in case it helps inform future decisions.

Thank you for your time
