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".

Implementors

impl<'a, E: Expr<'a, PostgresValue<'a>>> JsonExprExt<'a> for E
