Cargo Features

[dependencies]
wasm-bindgen-test = { version = "0.3.49", default-features = false, features = ["std", "gg-alloc"] }
default = std

The std feature is set by default whenever wasm-bindgen-test is added without default-features = false somewhere in the dependency tree.

std default = scoped-tls

Enables std of js-sys, wasm-bindgen, and wasm-bindgen-futures

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.

gg-alloc implicit feature

Enables gg-alloc

gg-alloc:

A custom allocator that only returns pointers above 2G

scoped-tls std
