aleo-std

aleo-std is a standard library of tools for use in AleoHQ repositories.

Usage Guide

To use this crate to your repository, add the following to your Cargo.toml: toml [dependencies.aleo-std] version = "0.1"

CPU

rust fn foo() { // Prints the CPU name. println!("{:?}", aleo_std::get_cpu()); }

Storage

```rust use aleo_std::prelude::*;

fn foo() { // Prints the Aleo directory. println!("{:?} exists: {:?}", aleodir(), aleodir().exists()); // Prints the Aleo ledger directory in production mode. println!("{:?} exists: {:?}", aleoledgerdir(2, None), aleoledgerdir(2, None).exists()); // Prints the Aleo operator directory in production mode. println!("{:?} exists: {:?}", aleooperatordir(2, None), aleooperatordir(2, None).exists()); // Prints the Aleo prover directory in production mode. println!("{:?} exists: {:?}", aleoproverdir(2, None), aleoproverdir(2, None).exists()); } ```

Time

```rust use aleo_std::prelude::*;

[time]

fn foo() -> u32 { // Insert expensive operation 1 + 1 } ```

Timed

```rust use aleo_std::prelude::*;

[timed]

fn foo(y: i32) -> i32 { let mut x = 1; let d = 1_000; x += d; x += y; x }

[timed]

fn main() { foo(23); } ```

Timer

```rust use aleo_std::prelude::*;

fn foo() -> u32 { // Start the timer. let timer = timer!("Arithmetic");

// Insert expensive operation
let x = 1 + 1;

// Print the elapsed time up to this point.
lap!(timer);

// Insert expensive operation
let y = 1 + 1;

// Print the total time elapsed.
finish!(timer);

x + y

} ```
