C API for graphql-idl-parser

This is an FFI binding to the graphql-idl-parser crate, which allows you to use that crate in your C project.

The header file (includes/gql-idl-parser.h) serves as the primary API documentation of this library. T

Usage

There are examples on how to use this in C in the example and test sub-directories.

Simply running cargo build --release should generate the .so or .dylib for you.

Assuming you have a C compiler, then this should work to run the example:

$ git clone git://github.com/gjtorikian/graphql-idl-parser
$ ./compile

Here's a general usage example:

#include "gql-idl-parser.h"

int main()
{
  GraphQLTypes* types = NULL;
  size_t types_len = 0;
  uint8_t err;

  err = gqlidl_parse_schema("# Yeah yeah\nscalar DateTime\ntype OMG {}", &types, &types_len);

  if (err > 0) {
    printf("Error: Return code %d", err);
    exit(err);
  }

  for (size_t i = 0; i < types_len; i++) {
    // ...
  }
}
