Struct Annotation 

pub struct Annotation { /* private fields */ }

Represents an annotation for annotations constraint.

Grammar: <ANNOTATION> ::= <SYMBOL>
               | required::<SYMBOL>
               | optional::<SYMBOL>

Implementations

impl Annotation

pub fn new(value: String, is_required: bool, isl_version: IslVersion) -> Self

pub fn value(&self) -> &String

pub fn is_required(&self) -> bool

Trait Implementations

impl Clone for Annotation

fn clone(&self) -> Annotation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Annotation

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

Formats the value using the given formatter.

impl PartialEq for Annotation

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

impl WriteAsIon for Annotation

fn write_as_ion<V: ValueWriter>(&self, writer: V) -> IonResult<()>

Maps this value to the Ion data model using the provided ValueWriter implementation.

fn encode_as<E, C>( &self, config: C, ) -> Result<<E as Encoding>::Output, IonError>

where E: Encoding, C: Into<WriteConfig<E>>, &'a Self: for<'a> WriteAsIon,

Encodes this value as an Ion stream with self as the single top-level value. If the requested encoding is binary of any version, returns a Vec<u8> containing the encoded bytes. If the requested encoding is text of any version, returns a String instead.

fn encode_to<E, C, W>(&self, config: C, output: W) -> Result<W, IonError>

where E: Encoding, C: Into<WriteConfig<E>>, W: Write, &'a Self: for<'a> WriteAsIon,

Encodes this value as an Ion stream with self as the single top-level value, writing the resulting stream to the specified output.
