Enum IonTypeCode

pub enum IonTypeCode {
    NullOrNop,
    Boolean,
    PositiveInteger,
    NegativeInteger,
    Float,
    Decimal,
    Timestamp,
    Symbol,
    String,
    Clob,
    Blob,
    List,
    SExpression,
    Struct,
    AnnotationOrIvm,
    Reserved,
}

Represents the type information found in the header byte of each binary Ion value. While this value can be readily mapped to a user-level IonType, it is a distinct concept. The IonTypeCode enum captures system-level information that is not exposed to end users of the library, including:

• Whether the cursor is positioned over whitespace that needs to be skipped.
• Whether the integer value being read is positive or negative.
• Whether the next type code is reserved.

See the Typed Value Formats section of the spec for more information.

Implementations

impl IonTypeCode

pub const fn to_u8(self) -> u8

Constant function to convert an IonTypeCode into a u8.

Trait Implementations

impl Clone for IonTypeCode

fn clone(&self) -> IonTypeCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IonTypeCode

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

Formats the value using the given formatter.

impl PartialEq for IonTypeCode

fn eq(&self, other: &IonTypeCode) -> 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.

impl TryFrom<IonTypeCode> for IonType

fn try_from(ion_type_code: IonTypeCode) -> Result<Self, Self::Error>

Attempts to convert the system-level IonTypeCode into the corresponding user-level IonType.

type Error = IonError

The type returned in the event of a conversion error.

impl TryFrom<u8> for IonTypeCode

fn try_from(type_code: u8) -> Result<Self, Self::Error>

Attempts to convert the provided byte into an IonTypeCode. Any value greater than 15 will result in an Error.

type Error = IonError

The type returned in the event of a conversion error.
