WHERE operators (FraiseQL v1 compatibility).

All operators from v1 are supported for backwards compatibility. No underscore prefix (e.g., eq, icontains, not _eq, _icontains).

Note: ExtendedOperator variants may contain f64 values which don’t implement Eq, so WhereOperator derives PartialEq only (not Eq).

Variants

Eq

Equal (=).

Neq

Not equal (!=).

Gt

Greater than (>).

Gte

Greater than or equal (>=).

Lt

Less than (<).

Lte

Less than or equal (<=).

In

In list (IN).

Nin

Not in list (NOT IN).

Contains

Contains substring (LIKE ‘%value%’).

Icontains

Contains substring (case-insensitive) (ILIKE ‘%value%’).

Startswith

Starts with (LIKE ‘value%’).

Istartswith

Starts with (case-insensitive) (ILIKE ‘value%’).

Endswith

Ends with (LIKE ‘%value’).

Iendswith

Ends with (case-insensitive) (ILIKE ‘%value’).

Like

Pattern matching (LIKE).

Ilike

Pattern matching (case-insensitive) (ILIKE).

IsNull

Is null (IS NULL or IS NOT NULL).

ArrayContains

Array contains (@>).

ArrayContainedBy

Array contained by (<@).

ArrayOverlaps

Array overlaps (&&).

LenEq

Array length equal.

LenGt

Array length greater than.

LenLt

Array length less than.

LenGte

Array length greater than or equal.

LenLte

Array length less than or equal.

LenNeq

Array length not equal.

CosineDistance

Cosine distance (<=>).

L2Distance

L2 (Euclidean) distance (<->).

L1Distance

L1 (Manhattan) distance (<+>).

HammingDistance

Hamming distance (<~>).

InnerProduct

Inner product (<#>). Higher values = more similar.

JaccardDistance

Jaccard distance for set similarity.

Matches

Full-text search (@@).

PlainQuery

Plain text query (plainto_tsquery).

PhraseQuery

Phrase query (phraseto_tsquery).

WebsearchQuery

Web search query (websearch_to_tsquery).

IsIPv4

Is IPv4.

IsIPv6

Is IPv6.

IsPrivate

Is private IP (RFC1918 ranges).

IsPublic

Is public IP (not private).

IsLoopback

Is loopback address (127.0.0.0/8 or ::1).

InSubnet

In subnet (<<) - IP is contained within subnet.

ContainsSubnet

Contains subnet (>>) - subnet contains another subnet.

ContainsIP

Contains IP (>>) - subnet contains an IP address.

Overlaps

Overlaps (&&) - subnets overlap.

StrictlyContains

Strictly contains (@>).

AncestorOf

Ancestor of (@>).

DescendantOf

Descendant of (<@).

MatchesLquery

Matches lquery (~).

MatchesLtxtquery

Matches ltxtquery (@) - Boolean query syntax.

MatchesAnyLquery

Matches any lquery (?).

DepthEq

Depth equal (nlevel() =).

DepthNeq

Depth not equal (nlevel() !=).

DepthGt

Depth greater than (nlevel() >).

DepthGte

Depth greater than or equal (nlevel() >=).

DepthLt

Depth less than (nlevel() <).

DepthLte

Depth less than or equal (nlevel() <=).

Lca

Lowest common ancestor (lca()).

Extended(ExtendedOperator)

Extended operator for rich scalar types (Email, VIN, CountryCode, etc.) These operators are specialized filters enabled via feature flags. See fraiseql_core::filters::ExtendedOperator for available operators.

Implementations

impl WhereOperator

pub fn from_str(s: &str) -> Result<Self>

Parse operator from string (GraphQL input).

Errors

Returns FraiseQLError::Validation if operator name is unknown.

pub const fn expects_array(&self) -> bool

Check if operator requires array value.

pub const fn is_case_insensitive(&self) -> bool

Check if operator is case-insensitive.

pub const fn is_string_operator(&self) -> bool

Check if operator works with strings.

Trait Implementations

impl Clone for WhereOperator

fn clone(&self) -> WhereOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WhereOperator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WhereOperator

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WhereOperator

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

impl Serialize for WhereOperator

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
