Crate aligned_sized

aligned-sized is a library providing the aligned_sized macro, which:

• Calculates a size of the given struct and provides a LEN constant with that value.

Future plans:

• Ensuring that the struct is aligned, adding padding fields when neccessary.

Motivation

Calculating the size of a struct is often a necessity when developing project in Rust, in particular:

• Solana programs, also when using Anchor framework.
• eBPF programs written in Aya.

This library provides a macro which automatically calculates the size, also taking in account factors which make a straightforward use of core::mem::size_of::<T> for the whole struct impossible (discriminants, vectors etc.).
