Macro bytes_to_type 

macro_rules! bytes_to_type {
    ($type:ty) => { ... };
}

Provides a macro to generate a function converting byte slices to vectors of a specified type.

The bytes_to_type! macro generates a conversion function that transforms a byte slice (&[u8]) into a Vec<T>, where T is a type specified as an argument to the macro. The resulting function returns a Result<Vec<T>, anyhow::Error> to gracefully handle potential conversion failures.

Example

use bytes_to_type::bytes_to_type;

// This macro generates a function with the signature:
// pub fn bytes_to_u32(bytes: &[u8]) -> Result<Vec<u32>, anyhow::Error>
bytes_to_type!(u32);

let bytes = vec![1, 2, 3, 4, 5, 6, 7, 8];
let result = bytes_to_u32(&bytes).expect("Failed to convert bytes to u32");

assert_eq!(result, vec![67305985, 134678021]);

Generated Function

The generated function ensures the safe conversion of byte slices into Vec<T> while preserving the byte order. If the length of the byte slice is not a multiple of the size of T or if the conversion fails due to other reasons, the function returns an Err variant containing an error message.

Usage Note

Be mindful of the byte order and potential alignment issues during conversions to prevent unintended results or panics during runtime.
