Trait Implementations

impl Array for JsonbArray

unsafe fn raw_value_at_unchecked(&self, idx: usize) -> Self::RefItem<'_>

Retrieve a reference to value regardless of whether it is null without checking the index boundary.

fn len(&self) -> usize

Number of items of array.

fn to_protobuf(&self) -> PbArray

impl Clone for JsonbArray

fn clone(&self) -> JsonbArray

Returns a copy of the value.

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

impl Debug for JsonbArray

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

Formats the value using the given formatter.

impl EstimateSize for JsonbArray

fn estimated_heap_size(&self) -> usize

The estimated heap size of the current struct in bytes.

fn estimated_size(&self) -> usize

where Self: Sized,

The estimated total size of the current struct in bytes, including the estimated_heap_size and the size of Self.

impl<'a> From<&'a ArrayImpl> for &'a JsonbArray

fn from(array: &'a ArrayImpl) -> Self

Converts to this type from the input type.

impl From<&JsonbArray> for StringArray

fn from(array: &JsonbArray) -> Self

Converts to this type from the input type.

impl From<&JsonbArray> for StringArray

fn from(array: &JsonbArray) -> Self

Converts to this type from the input type.

impl From<&JsonbArray> for LargeStringArray

fn from(array: &JsonbArray) -> Self

Converts to this type from the input type.

impl From<&JsonbArray> for LargeStringArray

fn from(array: &JsonbArray) -> Self

Converts to this type from the input type.

impl From<ArrayImpl> for JsonbArray

fn from(array: ArrayImpl) -> Self

Converts to this type from the input type.

impl From<JsonbArray> for ArrayImpl

fn from(arr: JsonbArray) -> Self

impl FromIterator<JsonbVal> for JsonbArray

fn from_iter<I: IntoIterator<Item = JsonbVal>>(iter: I) -> Self

Creates a value from an iterator.

impl FromIterator<Option<JsonbVal>> for JsonbArray

fn from_iter<I: IntoIterator<Item = Option<JsonbVal>>>(iter: I) -> Self

impl PartialEq for JsonbArray

fn eq(&self, other: &JsonbArray) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
