Implementations

impl Backend

pub fn instrument_fn(&self, spec: Spec, func: ItemFn) -> Result<ItemFn>

impl Backend

pub fn instrument_trait( &self, spec: Spec, the_trait: ItemTrait, ) -> Result<ItemTrait>

Expand trait items by mangling each method and adding a wrapper default impl.

Mangling a function involves the following:

1. Rename the function following the pattern: fn add -> fn __anodized_add.
2. Make a new function with the original name that has a default impl; the default impl performs runtime validation and calls the mangled function.

pub fn instrument_trait_impl( &self, spec: Spec, the_impl: ItemImpl, ) -> Result<ItemImpl>

Expand impl items by mangling methods for trait impls

#[spec] attributes on the impl items themselves are not allowed.
