Fields

rustfmt: bool

Whether or not rustfmt is executed to format generated code.

std_feature: bool

If true, code generation should qualify any features that depend on std with cfg(feature = "std").

raw_strings: bool

If true, code generation should pass borrowed string arguments as &[u8] instead of &str. Strings are still required to be valid UTF-8, but this avoids the need for Rust code to do its own UTF-8 validation if it doesn’t already have a &str.

skip: Vec<String>

Names of functions to skip generating bindings for.

exports: HashMap<ExportKey, String>

Names of the concrete types which implement the traits representing any functions, interfaces, and/or resources exported by the world.

Example: --exports world=MyWorld,ns:pkg/iface1=MyIface1,ns:pkg/iface1/resource1=MyResource1,

stubs: bool

If true, generate stub implementations for any exported functions, interfaces, and/or resources.

export_prefix: Option<String>

Optionally prefix any export names with the specified value.

This is useful to avoid name conflicts when testing.

ownership: Ownership

Whether to generate owning or borrowing type definitions.

Valid values include:

• owning: Generated types will be composed entirely of owning fields, regardless of whether they are used as parameters to imports or not.

• borrowing: Generated types used as parameters to imports will be “deeply borrowing”, i.e. contain references rather than owned values when applicable.

• borrowing-duplicate-if-necessary: As above, but generating distinct types for borrowing and owning, if necessary.

runtime_path: Option<String>

The optional path to the wit-bindgen runtime module to use.

This defaults to wit_bindgen::rt.

bitflags_path: Option<String>

The optional path to the bitflags crate to use.

This defaults to wit_bindgen::bitflags.

additional_derive_attributes: Vec<String>

Additional derive attributes to add to generated types. If using in a CLI, this flag can be specified multiple times to add multiple attributes.

These derive attributes will be added to any generated structs or enums

with: HashMap<String, String>

Remapping of interface names to rust module names.
