Enum RawStreamItem

pub enum RawStreamItem {
    VersionMarker(u8, u8),
    Value(IonType),
    Null(IonType),
    Nothing,
}

Raw stream components that a RawReader may encounter.

Variants

VersionMarker(u8, u8)

An Ion Version Marker (IVM) indicating the Ion major and minor version that were used to encode the values that follow.

Value(IonType)

A non-null Ion value and its corresponding Ion data type. Stream values that represent system constructs (e.g. a struct marked with a $ion_symbol_table annotation) are still considered values at the raw level.

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 RawStreamItem

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

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

Trait Implementations

impl Clone for RawStreamItem

fn clone(&self) -> RawStreamItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RawStreamItem

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

Formats the value using the given formatter.

impl Display for RawStreamItem

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

Formats the value using the given formatter.

impl PartialEq for RawStreamItem

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

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

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

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