Cargo Features

cranelift-wasm = { version = "0.107.0", default-features = false, features = ["std", "core", "enable-serde"] }
default = std

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

std default

Enables std of cranelift-frontend and cranelift-codegen


The "std" feature enables use of libstd. The "core" feature enables use of some minimal std-like replacement libraries. At least one of these two features need to be enabled.

core = hashbrown

Enables core of cranelift-codegen and cranelift-frontend


The "core" feature used to enable a hashmap workaround, but is now deprecated (we (i) always use hashbrown, and (ii) don't support a no_std build anymore). The feature remains for backward compatibility as a no-op.

enable-serde = serde, serde_derive

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.

hashbrown core?
serde enable-serde?
serde_derive enable-serde?
