Enum Found 

pub enum Found {
    At(u32),
    Absent,
}

Where one literal sits in a dictionary that came with its sorted order.

Variants

At(u32)

The dictionary holds the literal under this code, so a row matches exactly when its code is this one.

Absent

The dictionary does not hold the literal at all, so no row of this column matches it. This is the case a whole scan can sometimes be skipped on, and it costs the same search to find.
