=============================================================================

Features for the Wasmtime CLI executable

Note that many of these features are inherited from Wasmtime itself or otherwise configure the wasmtime crate's execution. Features are provided as compile-time switches to disable functionality primarily if one is interested in configuring binary size and or exploring the binary size implications of various features. Most features are enabled by default but most embeddings likely won't need all features.

default = addr2line, cache, compile, component-model, config, coredump, cranelift, debug-builtins, demangle, explore, logging, old-cli, parallel-compilation, pooling-allocator, profiling, serve, wasi-http, wasi-nn, wasi-threads, wast, wat

These default features are set whenever wasmtime-cli is added without default-features = false somewhere in the dependency tree.

Enables clap
