* Minor tweak at how [export.exclude] is handled to allow excluding generic
instantiations in C mode. (#501)
* Documented cpp_compat option. (#496)
* Fixed a panic when parsing associated constants for a built-in type. (#494)
This is needed when running tests with clang/clang++, as some of the tests have
errors that clang reports which gcc does not such as unused static const
variables.
Functions will be fully exported when they are `pub, `no_mangle`, and `extern
"C"`. Only two cases we should not generate warning which are `pub, `no_mangle`,
and `extern "C"` are all enabled or disabled.
* Support 'swift_name' attributes on generated functions (#449)
* Add [export.pre_body] to config (#452)
* Handle new line in doc attribute (#454)
* Add support for `Self` in tagged enums, structs and unions (#455, #455, #456)
* Make sentinel variant respect regular config (#459)
* Fix layout of tagged enums with size under some configurations (#463)
* Add an option to allow configuring the order of function names in generated headers (#466)
Thanks to all the awesome contributors.
This affected cases where the style was set to `Stle::Tag`.
In enumerations, do not emut the tag type name with an `enum`
prefix. C treats the `enum` type as an `int` even if the
representation should be something else.
Here's an example non-C-like-enumeration:
#[repr(C, u8)]
enum P {
P1(u8),
P2(u8, u8),
P3(u8, u8, u8),
}
Without this patch, this is what's generated:
enum P_Tag {
P1,
P2,
P3,
};
typedef uint8_t P_Tag;
typedef struct {
uint8_t _0;
} P1_Body;
typedef struct {
uint8_t _0;
uint8_t _1;
} P2_Body;
typedef struct {
uint8_t _0;
uint8_t _1;
uint8_t _2;
} P3_Body;
typedef struct {
enum P_Tag tag;
union {
P1_Body p1;
P2_Body p2;
P3_Body p3;
};
} P;
Rust expects the size of the type to be 4 (one for the discriminant,
and 3 for the widest alternative. C, however, treats the `enum P_Tag
tag` field as an `int` rather than a `uint8_t`. This puts the size
(with padding) of of `P` to 8 bytes instead of 4. When passing this
type between Rust and C, they will disagree on the size.
After the patch is applied, the `P` struct is properly defined:
typedef struct {
P_Tag tag;
union {
P1_Body p1;
P2_Body p2;
P3_Body p3;
};
} P;
