Enum ion_rs::reader::StreamItem

pub enum StreamItem {
    Value(IonType),
    Null(IonType),
    Nothing,
}

Stream components that an application-level Reader implementation may encounter.

Variants

Value(IonType)

A non-null Ion value and its corresponding Ion data type.

Null(IonType)

A null Ion value and its corresponding Ion data type.

Nothing

Indicates that the reader is not positioned over anything. This can happen:

• before the reader has begun processing the stream.
• after the reader has stepped into a container, but before the reader has called next()
• after the reader has stepped out of a container, but before the reader has called next()
• after the reader has read the last item in a container

Implementations

impl StreamItem

pub fn nullable_value(ion_type: IonType, is_null: bool) -> StreamItem

If is_null is true, returns StreamItem::Value(ion_type). Otherwise, returns StreamItem::Null(ion_type).

Trait Implementations

impl Clone for StreamItem

fn clone(&self) -> StreamItem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StreamItem

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

Formats the value using the given formatter.

impl Display for StreamItem

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

Formats the value using the given formatter.

impl PartialEq<StreamItem> for StreamItem

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

This method tests for self and other values to be equal, and is used by ==.

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

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