Struct Filter 

pub struct Filter<'a> {
    pub field: usize,
    pub test: &'a dyn Fn(&[u8]) -> bool,
}

A non-scoring predicate over a document’s stored values.

The test takes raw bytes because this crate does not know what a number or a date is; the caller coerces. A document with no value for the field never passes — absent is not a value.

Fields

field: usize

Which declared value field the predicate reads.

test: &'a dyn Fn(&[u8]) -> bool

The test applied to that field’s bytes.
