pub enum PredicateOp {
    Eq,
    Ne,
    StartsWith,
    EndsWith,
    Contains,
    RegexMatch,
    RegexNoMatch,
}

Predicate operator for node text filtering.

Variants

Eq

== - equals

Ne

!= - not equals

StartsWith

^= - starts with

EndsWith

$= - ends with

Contains

*= - contains

RegexMatch

=~ - regex match

RegexNoMatch

!~ - regex no match

Implementations

impl PredicateOp

pub fn from_byte(b: u8) -> PredicateOp

Decode from bytecode representation.

pub fn to_byte(self) -> u8

Encode for bytecode.

pub fn as_str(self) -> &'static str

Operator as display string.

pub fn is_regex_op(&self) -> bool

Check if this is a regex operator.

Trait Implementations

impl Clone for PredicateOp

fn clone(&self) -> PredicateOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PredicateOp

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

Formats the value using the given formatter.

impl Hash for PredicateOp

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PredicateOp

fn eq(&self, other: &PredicateOp) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
