Struct JsonValues 

pub struct JsonValues<'a> { /* private fields */ }

The values of a JSON column, readable as JSONB or as text whichever encoding they arrived in.

Code that computes on JSON, such as tokenizers and indices, reads values through this type, so its behavior does not depend on whether they come from storage or from a caller.

Implementations

impl<'a> JsonValues<'a>

pub fn try_new(field: &ArrowField, array: &'a ArrayRef) -> Option<Self>

Read array as the values of field, or None when field does not hold JSON.

pub fn encoding(&self) -> JsonEncoding

pub fn to_jsonb(&self) -> Result<LargeBinaryArray, ArrowError>

The values as JSONB. Text values are parsed, so invalid JSON fails.

pub fn to_text(&self) -> ArrayRef

The values as JSON text: the input array when it already holds text, otherwise LargeUtf8 decoded from JSONB.

Trait Implementations

impl<'a> Clone for JsonValues<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for JsonValues<'a>

impl<'a> Debug for JsonValues<'a>

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

Formats the value using the given formatter.
