ValueFilter

Enum ValueFilter 

Source
pub enum ValueFilter<'a> {
    Range {
        field: &'a [u8],
        min: &'a [u8],
        max: &'a [u8],
    },
    Eq {
        field: &'a [u8],
        value: &'a [u8],
    },
}
Expand description

One FILTER predicate: which stored value field it reads, and the test on it — the wire’s RANGE / EQ shapes, in-process.

The bounds are raw bytes and are coerced with the type the field was DECLARED as, so a numeric range compares numerically rather than lexicographically.

Variants§

§

Range

field between min and max, both inclusive.

Fields

§field: &'a [u8]

The declared value field to read.

§min: &'a [u8]

Lower bound, inclusive.

§max: &'a [u8]

Upper bound, inclusive.

§

Eq

field exactly value.

Fields

§field: &'a [u8]

The declared value field to read.

§value: &'a [u8]

The value to match.
