davxy opened Issue #2728:
Hi there, I'm using your Rust implementation.
I'm having hard times trying to pass a structure reference from the host (before entering the wasm) to a host function (called from the wasm).
The idea is to be able to fetch a reference to the data once I'm in the host function callback (actually a solution can be pass the data as a serialized byte array, but that option has been excluded for performance reasons).
Is there a way to attach a reference to my structure to the
Caller
structure that I receive in the host function?I think that the issue has already being partially covered by #2491 (using lambdas) . But I was wandering if some other alternative method is available.
Thank you so much for your awesome work

The next release of wasmtime will let you configure
Store
-specific context data, and you can get theStore
from aCaller

Awesome!!!
Just to know how to move with my project (i.e. wait for the release or make a temporary hack). When do you think that the new version will be published on
crates.io
?
No pressure :-)Thanks a lot

I'll double check with the team to see if there's anything we need to finish up first before we can cut a new release.
In the meantime, you can add this to your
Cargo.toml
:[patch.crates-io] wasmtime = { git = "https://github.com/bytecodealliance/wasmtime.git", branch = "main" } # And do the same for any other wasmtime crates you're using that need to be # the same version, eg `wasmtime-wasi`

wasmtime 0.25.0 is now published on crates.io: https://crates.io/crates/wasmtime/0.25.0
