Struct repr::adt::jsonb::JsonbPacker

pub struct JsonbPacker {
    row: Row,
}

A JSON deserializer that decodes directly into an existing Row.

The JsonbPacker takes ownership of the Row and returns ownership after successfully packing one JSON object. Packing multiple JSON objects in sequence requires constructing multiple JsonbPackers. This somewhat irritating API is required to preserve the safety properties of the Row, which require that no one observe the state of the Row after a decoding error.

Fields

row: Row

Implementations

impl JsonbPacker

pub fn new(row: Row) -> JsonbPacker

Constructs a new JsonbPacker that will pack into row.

pub fn pack_serde_json(self, val: Value) -> Result<Row, Error>

Packs a serde_json::Value.

Errors if any of the contained integers cannot be represented exactly as an f64.

pub fn pack_slice(self, buf: &[u8]) -> Result<Row, Error>

Parses and packs a JSON-formatted byte slice.

Errors if the slice is not valid JSON or if any of the contained integers cannot be represented exactly as an f64.

pub fn pack_str(self, s: &str) -> Result<Row, Error>

Parses and packs a JSON-formatted string.

Errors if the string is not valid or JSON or if any of the contained integers cannot be represented exactly as an f64.
