Struct mz_repr::adt::jsonb::JsonbRef

source ·
pub struct JsonbRef<'a> { /* private fields */ }
Expand description

A borrowed JSON value.

JsonbRef is to Jsonb as &str is to String.

Implementations§

source§

impl<'a> JsonbRef<'a>

source

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.

source

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

Unwrapps a JsonbRef and returns the inner Datum.

source

pub fn to_owned(&self) -> Jsonb

Constructs an owned Jsonb from this JsonbRef.

source

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.

source

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.
