Cargo Features
tokio_wasi has no features set by default.
[dependencies]
tokio_wasi = { version = "1.25.2", features = ["full", "fs", "io-util", "io-std", "macros", "net", "process", "rt", "rt-multi-thread", "signal", "time", "test-util", "stats", "tracing"] }
- default
-
Include nothing by default
- full = fs, io-std, io-util, macros, net, parking_lot, process, rt, rt-multi-thread, signal, sync, time
-
enable everything
- fs full?
- io-util full? = bytes, memchr
- io-std full?
-
stdin, stdout, stderr
- macros full? = tokio-macros
- net full? = libc, socket2, wasmedge_wasi_socket
-
Enables Win32_Security, Win32_Storage_FileSystem, Win32_System_Pipes and Win32_System_SystemServices of windows-sys ^0.45 and os-ext of mio_wasi
mio_wasi:
Enables additional OS specific extensions, e.g. Unix
pipe(2)
. - process full? = bytes, libc, signal-hook-registry
-
Enables os-ext of mio_wasi, Win32_System_Threading and Win32_System_WindowsProgramming of windows-sys ^0.45
- rt full? rt-multi-thread? test-util?
-
Includes basic task execution capabilities
- rt-multi-thread full? = num_cpus, rt
- signal full? = libc, signal-hook-registry
-
Enables os-ext of mio_wasi, Win32_System_Console of windows-sys ^0.45
- sync time full? test-util?
- test-util = rt, sync, time
- stats
-
Technically, removing this is a breaking change even though it only ever did anything with the unstable flag on. It is probably safe to get rid of it after a few releases.
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.
- tokio-macros macros?
-
Enables tokio-macros ^1.7.0
- bytes io-util? process?
-
Enables bytes
Everything else is optional...
- memchr io-util?
- mio_wasi net? process? signal?
- num_cpus rt-multi-thread?
- parking_lot full?
- tracing tokio_unstable implicit feature
-
Enables tracing
tracing:
Application-level tracing for Rust

… - socket2 not wasm32 wasm64 net?
-
Enables socket2 ^0.4.4
- wasmedge_wasi_socket wasi net?
- signal-hook-registry unix process? signal?
- libc unix net? process? signal?
- windows-sys docsrs win net? process? signal?
-
