Fields

rustfmt: bool

Whether or not rustfmt is executed to format generated code.

tracing: bool

Whether or not to emit tracing macro calls on function entry/exit.

async_: bool

Whether or not to use async rust functions and traits.

trappable_error_type: Vec<TrappableError>

A list of “trappable errors” which are used to replace the E in result<T, E> found in WIT.

duplicate_if_necessary: bool

Whether or not to generate “duplicate” type definitions for a single WIT type if necessary, for example if it’s used as both an import and an export.

only_interfaces: bool

Whether or not to generate code for only the interfaces of this wit file or not.

with: HashMap<String, String>

Remapping of interface names to rust module names. TODO: is there a better type to use for the value of this map?
