Macro switchboard_solana::program_id::require_keys_neq

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

Ensures two pubkeys are not equal.

Use require_neq to compare two non-pubkey values.

Can be used with or without a custom error code.

Example

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