Enum FilterOp 

pub enum FilterOp {
    Exists,
    Equals,
    NotEquals,
    WordMatch,
    StartsWith,
    EndsWith,
    Contains,
    GreaterThan,
    LessThan,
    GreaterOrEqual,
    LessOrEqual,
}

Comparison operators for property/attribute filters.

Used by both the record selector [prop op value] syntax and SchQL [attr op value] syntax.

Variants

Exists

[attr] - Has attribute (exists check)

Equals

= - Exact match (case-insensitive for strings)

NotEquals

!= - Not equal

WordMatch

~= - Word match (matches word in space-separated list)

StartsWith

^= - Starts with

EndsWith

$= - Ends with

Contains

*= - Contains substring

GreaterThan

> - Greater than (numeric)

LessThan

< - Less than (numeric)

GreaterOrEqual

>= - Greater or equal (numeric)

LessOrEqual

<= - Less or equal (numeric)

Implementations

impl FilterOp

pub fn try_parse(s: &str) -> Option<Self>

Parse operator from string representation.

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

Get the string representation of this operator.

Trait Implementations

impl Clone for FilterOp

fn clone(&self) -> FilterOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilterOp

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

Formats the value using the given formatter.

impl PartialEq for FilterOp

fn eq(&self, other: &FilterOp) -> 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.
