def_oid is a procedural macro. It will run at compile time and transform your program's source code.

Adding `def_oid` macro(s) as a dependency

Run this command in a terminal, in your project's directory:

cargo add def_oid

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

def_oid = "1.0.0"

You may need to import the macro(s) with use def_oid::*.

Read the def_oid documentation.

Readme

def_oid

Why yet another OID crate ? This library allow a compile time OID encoded bytes by using one of the two procedural macros oid and const_oid. Both macro gives a fixed size array of u8 so it's no runtime overhead.

Use case

oid is used to get a fixed size bytes of OID. It can be used as expression.

some_function(oid!("2.5.4.3")); // some_function will received [85, 4, 3] of type [u8; 3].

const_oid is used to declare fixed size bytes constant variable. This is useful for global const declaration.

const_oid!(COMMON_NAME, "2.5.4.3"); // Declare const variable "COMMON_NAME" with type [u8; 3]
println!("{:?}", COMMON_NAME); // it should print [85, 4, 3]
