- Typhoon is in active development, so all APIs are subject to change.

To get started with Typhoon, add it to your Rust project using Cargo:
cargo add typhoonHere’s a quick example to show how Typhoon simplifies Solana program development:
#![no_std]
use {
bytemuck::{AnyBitPattern, NoUninit},
typhoon::prelude::*,
};
program_id!("Fg6PaFpoGXkYsidMpWTK6W2BeZ7FEfcYkg476zPFsLnS");
nostd_panic_handler!();
no_allocator!();
#[context]
pub struct InitContext {
pub payer: Mut<Signer>,
#[constraint(
init,
payer = payer,
)]
pub counter: Mut<Account<Counter>>,
pub system: Program<System>,
}
#[context]
pub struct CounterMutContext {
pub counter: Mut<Account<Counter>>,
}
#[context]
pub struct DestinationContext {
pub destination: Mut<SystemAccount>,
}
handlers! {
initialize,
increment,
close
}
pub fn initialize(_: InitContext) -> ProgramResult {
Ok(())
}
pub fn increment(ctx: CounterMutContext) -> ProgramResult {
ctx.counter.mut_data()?.count += 1;
Ok(())
}
pub fn close(
CounterMutContext { counter }: CounterMutContext,
DestinationContext { destination }: DestinationContext,
) -> ProgramResult {
counter.close(&destination)?;
Ok(())
}
