Cargo Features

thin_main_loop has no features set by default.

thin_main_loop = { version = "0.2.0", features = ["glib", "win32", "web"] }
glib = glib-sys
win32 = winapi
web = js-sys, wasm-bindgen, web-sys

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.

wasm-bindgen web?
js-sys web?
glib-sys glib?

Enables glib-sys ^0.7

web-sys web?
winapi win32?
