Struct mz_repr::adt::jsonb::JsonbRef

pub struct JsonbRef<'a> {
    datum: Datum<'a>,
}

A borrowed JSON value.

JsonbRef is to Jsonb as &str is to String.

Fields

datum: Datum<'a>

Implementations

impl<'a> JsonbRef<'a>

pub fn from_datum(datum: Datum<'_>) -> JsonbRef<'_>

Constructs a JsonbRef from a Datum.

Note that datum is not checked for validity. Not all Datums are valid JSON.

pub fn into_datum(self) -> Datum<'a>

Unwraps a JsonbRef and returns the inner Datum.

pub fn to_owned(&self) -> Jsonb

Constructs an owned Jsonb from this JsonbRef.

pub fn to_writer<W>(&self, writer: W) -> Result<(), Error>

where W: Write,

Serializes the JSON value into the given IO stream.

Panics

Panics if this JsonbRef was constructed with a Datum that is not representable as JSON.

pub fn to_serde_json(&self) -> Value

Constructs an owned serde_json::Value from this JsonbRef.

Panics

Panics if this JsonbRef was constructed with a Datum that is not representable as JSON.

Trait Implementations

impl<'a> AsColumnType for JsonbRef<'a>

fn as_column_type() -> ColumnType

The SQL column type of this Rust type

impl<'a> Clone for JsonbRef<'a>

fn clone(&self) -> JsonbRef<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, E> DatumType<'a, E> for JsonbRef<'a>

fn nullable() -> bool

Whether this Rust type can represent NULL values

fn fallible() -> bool

Whether this Rust type can represent errors

fn try_from_result( res: Result<Datum<'a>, E>, ) -> Result<Self, Result<Datum<'a>, E>>

Try to convert a Result whose Ok variant is a Datum into this native Rust type (Self). If it fails the error variant will contain the original result.

fn into_result(self, _temp_storage: &'a RowArena) -> Result<Datum<'a>, E>

Convert this Rust type into a Result containing a Datum, or an error

impl<'a> Debug for JsonbRef<'a>

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

Formats the value using the given formatter.

impl Display for JsonbRef<'_>

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

Formats the value using the given formatter.
