Method wasm_features

crates/wasmtime/src/config.rs:874–878

Explicitly enables (and un-disables) a given set of [`WasmFeatures`]. Note: this is a low-level method that does not necessarily imply that wasmtime _supports_ a feature. It should only be used to _disable_ features that callers want to be rejected by the parser or _enable_ features callers are certain that the current configuration of wasmtime supports. Feature validation is deferred until an e

    /// [`Engine::new`](crate::Engine::new) to fail later, if the feature
    /// configuration isn't supported.
    pub fn wasm_features(&mut self, flag: WasmFeatures, enable: bool) -> &mut Self {
        self.enabled_features.set(flag, enable);
        self.disabled_features.set(flag, !enable);
