default = sys-default

The sys-default feature is set by default whenever wasmer-wasix is added without default-features = false somewhere in the dependency tree.

compiler

Deprecated. Kept it for compatibility

js js-default? test-js? = chrono, js-sys, wasm-bindgen, wasm-bindgen-futures, web-sys

Enables js of virtual-fs, js-default, js-serializable-module, wasm-types-polyfill and wat of wasmer and wasm_js of getrandom

getrandom:
Optional backend: wasm_js

This flag enables the wasm_js backend and uses it by default on wasm32 where the target_os is unknown. The getrandom_backend cfg may override this.

WARNING: We strongly recommend against enabling this feature in libraries (except for tests) since it is known to break non-Web WASM builds and further since the usage of wasm-bindgen causes significant bloat to Cargo.lock (on all targets).

The only exception to this rule: if your crate already unconditionally depends on wasm-bindgen or js-sys on "unknown" WASM targets then it's acceptable to enable this feature unconditionally.

js-default = js

test-js = js

Enables wat of wasmer

host-vnet sys?

Enables host-net of virtual-net

host-threads sys?

host-reqwest sys? = reqwest

Enables max_level_off and release_max_level_off of tracing

enable-serde = typetag

Enables wasmer-wasix-types and enable-serde of virtual-fs and wasmer

wasmer:
Optional

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

hyper webc_runner_rt_dproxy? webc_runner_rt_wcgi?

rusty_pool sys-thread?

typetag enable-serde?

chrono js?

wcgi webc_runner_rt_wcgi?
