error[E0412]: cannot find type `ProgramResult` in this scope

Question

use anchor_lang::prelude::*;

declare_id!("Fg6PaFpoGXkYsidMpWTK6W2BeZ7FEfcYkg476zPFsLnS");

#[program]
pub mod myepicproject {
  use super::*;
  pub fn start_stuff_off(ctx: Context<StartStuffOff>) -> ProgramResult {
    Ok(())
  }
}

#[derive(Accounts)]
pub struct StartStuffOff {}

I have the source rust code above and the error below.

error[E0412]: cannot find type `ProgramResult` in this scope

For more information about this error, try `rustc --explain E0412`.
error: could not compile `myepicproject` due to previous error

Have any suggestion?

Using Anchor

Answer 1

Try like that:

pub fn start_stuff_off(ctx: Context<StartStuffOff>) -> Result<()> {

Answer 2

this solves the issue. you have to explicitly import it

use anchor_lang::solana_program::entrypoint::ProgramResult;
