Solana Development Utilities

A collection of utilities and macros to enhance Solana program development, focusing on compute unit logging and instruction discriminant generation.

Features

Generate unique instruction discriminants for Anchor programs
Log compute units for functions and code blocks
Utility functions for Solana-specific operations

Installation

Add the following to your Cargo.toml:

[dependencies]
sol_dev_utils = "0.1.0"
sol_dev_macros = "0.1.0"
sol_dev_proc_macros = "0.1.0"

Usage

Instruction Discriminants

Handles the global namespace automatically if no namespace is provided.

use sol_dev_proc_macros::anchor_discriminant;

match discriminant {
    anchor_discriminant![initialize] => initialize(),
    // This is equivalent to:
    // anchor_discriminant![global:initialize] => initialize(),
    anchor_discriminant![process] => process(),
    anchor_discriminant![custom:finalize] => finalize(),
    _ => return Err(ProgramError::InvalidInstructionData.into()),
}

Compute Unit Logging

Function-level logging

use sol_dev_proc_macros::compute_fn;

#[compute_fn]
fn some_fn() {
    // Function body
}

Code block logging

use sol_dev_macros::compute_fn;

compute_fn!("My Operation" => {
    // Your code here
    some_fn();
});
