Variants

LabelEq

Label at field index equals value

Fields

field: usize

value: u64

LabelIn

Label at field index is in set

Fields

field: usize

values: HashSet<u64>

LabelLt

Label at field index less than value

Fields

field: usize

value: u64

LabelGt

Label at field index greater than value

Fields

field: usize

value: u64

LabelRange

Label at field index in range [min, max]

Fields

field: usize

min: u64

max: u64

And(Vec<Filter>)

Logical AND of filters

Or(Vec<Filter>)

Logical OR of filters

None

No filter (match all)

Implementations

impl Filter

pub fn label_eq(field: usize, value: u64) -> Self

Create equality filter

pub fn label_in(field: usize, values: impl IntoIterator<Item = u64>) -> Self

Create “in set” filter

pub fn label_lt(field: usize, value: u64) -> Self

Create less-than filter

pub fn label_gt(field: usize, value: u64) -> Self

Create greater-than filter

pub fn label_range(field: usize, min: u64, max: u64) -> Self

Create range filter [min, max] inclusive

pub fn and(filters: Vec<Filter>) -> Self

Combine filters with AND

pub fn or(filters: Vec<Filter>) -> Self

pub fn matches(&self, labels: &[u64]) -> bool

Check if a label vector matches this filter

Trait Implementations

impl Clone for Filter

fn clone(&self) -> Filter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Filter

fn fmt(&self, f: &mut Formatter<'_>) -> Result
