A library for extracting #[repr(C)] pub structures

In order to expose a struct with stable ABI for interoperability with other programming languages, Rust developers should use #[repr(C)] attribute.

```rust

[repr(C)]

pub struct Great {

} ```

You can read about it more here

This library allows to perform syn-driven parsing for obtaining the information about location of these repr-c-pub-structs.

Example

src/main.rs

rust use repr_c_pub_struct::parse_for_repr_c_pub_structs; fn main() { let crate_root = std::env::var("CARGO_MANIFEST_DIR").unwrap(); let repr_c_structs = parse_for_repr_c_pub_structs(crate_root.as_str()); println!("{:#?}", repr_c_structs); }

src/unused.rs

```rust

[repr(C)]

pub struct Unused { // Test } ```

Output on Windows

text [ ParsedFile { path: "...\\repr_c_pub_struct\\src\\lib.rs", repr_c_pub_structs: ReprCPubStructs( [], ), }, ParsedFile { path: "...\\repr_c_pub_struct\\src\\main.rs", repr_c_pub_structs: ReprCPubStructs( [], ), }, ParsedFile { path: "...\\repr_c_pub_struct\\src\\unused.rs", repr_c_pub_structs: ReprCPubStructs( [ LineColumnEnds { start_line: 1, start_column: 0, end_line: 4, end_column: 1, }, ], ), }, ]

Note

The paths will be absolute. The prefixes have been deleted intentionally.

Seralization & Deserialization

All structures in this library implement Serialize and Deserialize traits from serde. Because of that you can convert into many data formats supporting serde.

Data formats

• [JSON], the ubiquitous JavaScript Object Notation used by many HTTP APIs.
• [Bincode], a compact binary format used for IPC within the Servo rendering engine.
• [CBOR], a Concise Binary Object Representation designed for small message size without the need for version negotiation.
• [YAML], a self-proclaimed human-friendly configuration language that ain't markup language.
• [MessagePack], an efficient binary format that resembles a compact JSON.
• [TOML], a minimal configuration format used by [Cargo].
• [Pickle], a format common in the Python world.
• [RON], a Rusty Object Notation.
• [BSON], the data storage and network transfer format used by MongoDB.
• [Avro], a binary format used within Apache Hadoop, with support for schema definition.
• [JSON5], a superset of JSON including some productions from ES5.
• [Postcard], a no_std and embedded-systems friendly compact binary format.
• [URL] query strings, in the x-www-form-urlencoded format.
• [Envy], a way to deserialize environment variables into Rust structs. (deserialization only)
• [Envy Store], a way to deserialize [AWS Parameter Store] parameters into Rust structs. (deserialization only)
• [S-expressions], the textual representation of code and data used by the Lisp language family.
• [D-Bus]'s binary wire format.
• [FlexBuffers], the schemaless cousin of Google's FlatBuffers zero-copy serialization format.
• [DynamoDB Items], the format used by [rusoto_dynamodb] to transfer data to and from DynamoDB.
