# Features for the Wasmtime crate.
#
# This section contains the compile-time features of the `wasmtime` crate. These
# features can be used to add more functionality and APIs exposed from the
# crate's API. Most of them are enabled by default. Disabling features can be
# done to cut down on binary size by disabling features that are not required
# for a particular embedding.

# precompiled WebAssembly modules.

# Enables support for winch, the WebAssembly baseline compiler. The Winch compiler
# strategy in `Config` will be available. It is currently in active development

# Enable support for garbage collection-related things.

# * Garbage collection: https://github.com/WebAssembly/gc
