Cargo Features

[dependencies]
gear-wasm = { version = "0.45.1", default-features = false, features = ["std", "reduced-stack-buffer", "atomics", "simd", "sign_ext", "bulk", "multi_value"] }

default = std

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

std default

This feature is useful when integrating on resource constrained devices such as microcontroler where the stack size is fixed (stacks do not grow) and limited to a few (k)bytes.
