🚀 Getting Started

Here’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!();
entrypoint!();

pub const ROUTER: EntryFn = basic_router! {
    0 => initialize,
    1 => increment,
    2 => close,
};


#[context]
pub struct InitContext {
    pub payer: Mut<Signer>,
    #[constraint(
        init,
        payer = payer,
    )]
    pub counter: Mut<SignerNoCheck<Account<Counter>>>,
    pub system: Program<System>,
}

#[context]
pub struct CounterMutContext {
    pub counter: Mut<Account<Counter>>,
}

#[context]
pub struct DestinationContext {
    pub destination: Mut<SystemAccount>,
}

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(())
}

#[derive(NoUninit, AnyBitPattern, AccountState, Copy, Clone)]
#[repr(C)]
pub struct Counter {
    pub count: u64,
}
