Extension trait providing method-based JSON operators for PostgreSQL expressions.

Provided Methods

fn json_get( self, key: &'a str, ) -> SQLExpr<'a, PostgresValue<'a>, Json, Null, Scalar>

Get JSON object field by key (-> operator), returns JSON.

fn json_get_idx( self, index: i32, ) -> SQLExpr<'a, PostgresValue<'a>, Json, Null, Scalar>

Get JSON array element by index (-> operator), returns JSON.

fn json_get_text( self, key: &'a str, ) -> SQLExpr<'a, PostgresValue<'a>, Text, Null, Scalar>

Get JSON object field as text (->> operator).

fn json_get_text_idx( self, index: i32, ) -> SQLExpr<'a, PostgresValue<'a>, Text, Null, Scalar>

Get JSON array element as text (->> operator).

fn json_get_path( self, path: &'a str, ) -> SQLExpr<'a, PostgresValue<'a>, Json, Null, Scalar>

Get JSON object at path (#> operator), returns JSON.

fn json_get_path_text( self, path: &'a str, ) -> SQLExpr<'a, PostgresValue<'a>, Text, Null, Scalar>

Get JSON object at path as text (#>> operator).

fn jsonb_contains<R>( self, other: R, ) -> SQLExpr<'a, PostgresValue<'a>, Boolean, NonNull, Scalar>

where R: ToSQL<'a, PostgresValue<'a>>,

JSONB contains (@> operator).

fn jsonb_contained<R>( self, other: R, ) -> SQLExpr<'a, PostgresValue<'a>, Boolean, NonNull, Scalar>

where R: ToSQL<'a, PostgresValue<'a>>,

JSONB is contained by (<@ operator).

fn jsonb_exists_key( self, key: &'a str, ) -> SQLExpr<'a, PostgresValue<'a>, Boolean, NonNull, Scalar>

JSONB key exists (? operator).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
