Macro switchboard_solana::prelude::require_gt

macro_rules! require_gt {
    ($value1: expr, $value2: expr, $error_code: expr $(,)?) => { ... };
    ($value1: expr, $value2: expr $(,)?) => { ... };
}

Ensures the first NON-PUBKEY value is greater than the second NON-PUBKEY value.

To include an equality check, use require_gte.

Can be used with or without a custom error code.

Example

pub fn set_data(ctx: Context<SetData>, data: u64) -> Result<()> {
    require_gt!(ctx.accounts.data.data, 0);
    ctx.accounts.data.data = data;
    Ok(());
}
