Variants

Or

And

Eq

NotEq

IsDistinctFrom

v7.9.27b — PG a IS DISTINCT FROM b / a IS NOT DISTINCT FROM b. NULL-safe equality: NULL IS NOT DISTINCT FROM NULL → true, NULL IS DISTINCT FROM NULL → false. The non-NULL behaviour matches <> / = exactly. Common in PG-style JOIN ON predicates and pg_dump output.

IsNotDistinctFrom

Lt

LtEq

Gt

GtEq

Add

Sub

Mul

Div

L2Distance

pgvector L2 (Euclidean) distance <->. Defined for two vector operands of equal dimension; engine returns Value::Float(d).

InnerProduct

pgvector inner-product <#> — returns -Σ aᵢ bᵢ so “smaller = more similar” remains true (matches pgvector’s published convention).

CosineDistance

pgvector cosine distance <=> — 1 - (a·b)/(|a| |b|).

Concat

SQL string concatenation ||. NULL propagates.

JsonGet

v4.14 json -> key — element access by string key (object) or integer index (array). Returns a JSON value.

JsonGetText

v4.14 json ->> key — same access, returns the result as TEXT (unwraps a top-level JSON string; renders other scalars as their canonical text).

JsonGetPath

v6.4.5 json #> path_text — walk the path encoded as a PG text array literal like '{a,0,b}'. Returns JSON.

JsonGetPathText

v6.4.5 json #>> path_text — same walk, returns TEXT.

JsonContains

v6.4.5 json @> sub_json — containment. Returns BOOL; true when every key/value in sub_json is structurally present in the left side. Matches PG semantics (top-level + recursive).

Trait Implementations

impl Clone for BinOp

fn clone(&self) -> BinOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BinOp

impl Debug for BinOp

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

Formats the value using the given formatter.

impl Display for BinOp

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

Formats the value using the given formatter.

impl Eq for BinOp

impl PartialEq for BinOp

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