A binding generator for the rust language. It is ported from clay's bindgen.
- clang 3.4 and up
Note: The libclang.so has to be statically linked with LLVM or you will encounter issue 89. You can also use LD_PRELOAD=/path/to/libclang.so to workaround the problem.
$ cargo build
Note: This links with Apple's version of libclang on OS X by default. This can be changed by setting the LIBCLANG_PATH environment variable.
If you are running the command line tool you will also need to append this path to your DYLD_LIBRARY_PATH environment variable, which you might already have set if you have installed the Rust compiler outside of standard /usr/local path.
The default path on OS X is:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/
Or if you only have Xcode Command Line Tools installed:
export DYLD_LIBRARY_PATH=/Library/Developer/CommandLineTools/usr/lib
Usage: ./bindgen [options] input.h
Options:
-h or --help Display help message
-l <name> or -l<name> Link to a dynamic library, can be provided
multiple times
-static-link <name> Link to a static library
-framework-link <name> Link to a framework
-o <output.rs> Write bindings to <output.rs> (default stdout)
-match <name> Only output bindings for definitions from files
whose name contains <name>
If multiple -match options are provided, files
matching any rule are bound to
-builtins Output bindings for builtin definitions
(for example __builtin_va_list)
-allow-unknown-types Don't fail if we encounter types we do not support,
instead treat them as void
-emit-clang-ast Output the ast (for debugging purposes)
-override-enum-type <type> Override enum type, type name could be
uchar
schar
ushort
sshort
uint
sint
ulong
slong
ulonglong
slonglong
Options other than stated above are passed to clang
Usage: bindgen!([headers], [named options])
Options:
Option Name Type Default

link multiple strings
link_static multiple strings
link_framework multiple strings
match multiple strings
emit_builtins bool true
allow_unknown_types bool false
clang_args string

###Generate MySQL client bindings
bindgen -l mysql -match mysql.h -o mysql.rs /usr/include/mysql/mysql.h
or
echo '#include <mysql.h>' > gen.h
bindgen `mysql_config --cflags` -l mysql -match mysql.h -o mysql.rs gen.h
or
Cargo.toml
[dependencies.bindgen]

mod mysql_bindings {
bindgen!("/usr/include/mysql/mysql.h", match="mysql.h", link="mysql")
