}
Expand description

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.

Performs copy-assignment from source. Read more

Formats the value using the given formatter. Read more

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

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

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

The type returned in the event of a conversion error.

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