Crate sized_data

Sized data trait implementation for Solana programs using Anchor framework

This crate provides a trait and derive macro for calculating struct sizes at compile time, which is particularly useful when working with Solana account initialization.

Example

use sized_data::SizedData;
use anchor_lang::prelude::*;

#[derive(SizedData)]
pub struct UserAccount {
    pub authority: Pubkey,
    pub counter: u64,
}

#[derive(Accounts)]
pub struct Initialize<'info> {
    #[account(
        init,
        payer = user,
        space = UserAccount::size_padded()
    )]
    pub user_account: Account<'info, UserAccount>,
    #[account(mut)]
    pub user: Signer<'info>,
    pub system_program: Program<'info, System>,
}
