Memgraph Mage Rust Query Modules

rsmgp-sys stands for Rust Memgraph Procedures "system" library to develop query modules for Memgraph in Rust.

Adding a new Rust Memgraph query module is simple, just add the following to your Cargo.toml project file.

[lib]
name = "query_module_name"
crate-type = ["cdylib"]

Memgraph Rust query modules API uses CStr (&CStr) becuase that's the most compatible type between Rust and Memgraph engine. Rust String can validly contain a null-byte in the middle of the string (0 is a valid Unicode codepoint). This means that not all Rust strings can actually be translated to C strings. While interacting with the rsmgp API, built-in CStr or c_str library should be used because Memgraph query modules API only provides C strings.
