* Generate extern wrappers for inlined functions
If bindgen finds an inlined function and the
`--generate-extern-functions` options is enabled, then:
- It will generate two new source and header files with external
functions that wrap the inlined functions.
- Rerun `Bindings::generate` using the new header file to include these
wrappers in the generated bindings.
The following additional options were added:
- `--extern-function-suffix=<suffix>`: Adds <suffix> to the name of each
external wrapper function (`__extern` is used by default).
- `--extern-functions-file-name=<name>`: Uses <name> as the file name
for the header and source files (`extern` is used by default).
- `--extern-function-directory=<dir>`: Creates the source and header
files inside <dir> (`/tmp/bindgen` is used by default).
The C code serialization is experimental and only supports a very
limited set of C functions.
Fixes #1090.

* codegen: Look through typedefs to detect void return type.
And reuse a bit more code.
Should fix #2377, but needs a test (can't run tests atm).
* Add tests
* Run rustfmt
* Update changelog

The bug only affects virtual inheritance, so instead disable layout
tests in the test that we know is broken. Not generating layout tests is
wrong anyways, because the offset would be wrong.

Fixes #2008.
Example:
```c
enum Enum { Variant };
typedef int16_t Enum;
```
This is valid and idiomatic C (though not valid C++). `cbindgen` uses this idiom as the default C translation of Rust enums, the equivalent of what would be `enum Enum : int16_t { Variant };` in C++.
`bindgen header.h` before:
```rust
pub const Enum_Variant: Enum = 0;
pub type Enum = ::std::os::raw::c_uint;
pub type Enum = i16;
```
```console
error[E0428]: the name `Enum` is defined multiple times
--> generated.rs:3:1
|
2 | pub type Enum = ::std::os::raw::c_uint;
| --------------------------------------- previous definition of the type `Enum` here
3 | pub type Enum = i16;
| ^^^^^^^^^^^^^^^^^^^^ `Enum` redefined here
|
= note: `Enum` must be defined only once in the type namespace of this module
```
After:
```rust
pub const Enum_Variant: Enum = 0;
pub type Enum = i16;
```

This reverts commit e8ffb42ab66405ac56d04494a30e54b584f2d4dd and adds a new `--wrap-unsafe-ops` option as a workaround.
|
|
This method can be used to process comments and replace them with whatever the user wants.
|
|
This PR introduces a new non-exhaustive `struct` called `DeriveInfo` to be used as the sole argument of `ParseCallbacks::add_derives` with the purpose of being able to extend the information passed to this method in a backwards-compatible manner, meaning that adding new fields to `DeriveInfo` won't be a breaking change when releasing a new version.
|
|
Even though this change does name deduplication in a slower way, it
avoids name collisions without any breaking changes in the test suite.
Fixes #2202
|
|
This guarantees that bindings generated by `bindgen` compile even if the `unsafe_op_in_unsafe_fn` lint is denied.
|
|
* Add support for the `"C-unwind"` ABI
This allows using `"C-unwind"` as an ABI override if the rust target is
nightly.
|
|
* Add the `--override-abi` option.
This option can be used from the CLI with the <abi>:<regex> syntax and
it overrides the ABI of a function if it matches <regex>.
Fixes #2257
|
|
* Allow callback composition
Store all the callbacks added to the builder in a `Vec` so bindgen
invokes each one of them in a last-to-first manner.
