Anchor rust code snippet:

use anchor_lang::prelude::*;

#[program]
pub fn initialize(_ctx: Context<Initialize>) -> Result<()> {
    emit!(MyEvent {
        err_msg_code: 100
    });
    Ok(())
}

#[event]
pub struct MyEvent {
    pub err_msg_code: u32,
}

  • What happens exactly when a event gets triggered? For instance in your example would MyEvent struct be displayed in logMessages within the corresponding transaction? Commented Jan 6, 2023 at 8:35

    @PeterSchwarz Event is emitted so that it can be subscribe to by the clients. And it would not display in logMessages, for that u need to use msg macro. Commented Jun 14, 2023 at 17:19
