Trait Implementations

impl BinaryDecodable for HistoryUpdateType

fn decode<S: Read + ?Sized>( stream: &mut S, ctx: &Context<'_>, ) -> EncodingResult<Self>

Decodes an instance from the read stream. The decoding options contains restrictions set by the server / client on the length of strings, arrays etc. If these limits are exceeded the implementation should return with a BadDecodingError as soon as possible.

impl BinaryEncodable for HistoryUpdateType

fn byte_len(&self, ctx: &Context<'_>) -> usize

Returns the exact byte length of the structure as it would be if encode were called. This may be called prior to writing to ensure the correct amount of space is available.

fn encode<S: Write + ?Sized>( &self, stream: &mut S, ctx: &Context<'_>, ) -> EncodingResult<()>

Encodes the instance to the write stream.

fn override_encoding(&self) -> Option<BuiltInDataEncoding>

Override the extension object encoding used for this type. This only makes sense if the type can only ever be encoded using a single built-in encoding.

fn encode_to_vec(&self, ctx: &Context<'_>) -> Vec<u8>

Convenience method for encoding a message straight into an array of bytes. It is preferable to reuse buffers than to call this so it should be reserved for tests and trivial code.

impl Clone for HistoryUpdateType

fn clone(&self) -> HistoryUpdateType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HistoryUpdateType

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

Formats the value using the given formatter.

impl Default for HistoryUpdateType

fn default() -> Self

Returns the “default value” for a type.

impl From<HistoryUpdateType> for i32

fn from(value: HistoryUpdateType) -> i32

Converts to this type from the input type.

impl IntoVariant for HistoryUpdateType

fn into_variant(self) -> Variant

Convert self into a variant.

impl JsonDecodable for HistoryUpdateType

fn decode( stream: &mut JsonStreamReader<&mut dyn Read>, ctx: &Context<'_>, ) -> EncodingResult<Self>

Decode Self from a JSON stream.

impl JsonEncodable for HistoryUpdateType

fn encode( &self, stream: &mut JsonStreamWriter<&mut dyn Write>, ctx: &Context<'_>, ) -> EncodingResult<()>

Write the type to the provided JSON writer.

impl PartialEq for HistoryUpdateType

fn eq(&self, other: &HistoryUpdateType) -> 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 TryFrom<i32> for HistoryUpdateType

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Error>

Performs the conversion.

impl UaEnum for HistoryUpdateType

type Repr = i32

The numeric type used to represent this enum when encoded.

fn from_repr(repr: Self::Repr) -> Result<Self, Error>

Convert from a numeric value to an instance of this enum.

fn into_repr(self) -> Self::Repr

Convert this enum into its numeric representation.

fn as_str(&self) -> &'static str

Get the string representation of this enum, on the form [NAME]_[REPRESENTATION], i.e. KEY_1.

fn from_str(val: &str) -> Result<Self, Error>

Convert from the string representation of this enum to its value, on the form [NAME]_[REPRESENTATION], i.e. KEY_1.

impl UaNullable for HistoryUpdateType

fn is_ua_null(&self) -> bool

Return true if this value is null, meaning it can be left out when being encoded in JSON and XML encodings.

impl XmlDecodable for HistoryUpdateType

fn decode( stream: &mut XmlStreamReader<&mut dyn Read>, ctx: &Context<'_>, ) -> EncodingResult<Self>

Decode a value from an XML stream.

impl XmlEncodable for HistoryUpdateType

fn encode( &self, stream: &mut XmlStreamWriter<&mut dyn Write>, _ctx: &Context<'_>, ) -> EncodingResult<()>

Encode a value to an XML stream.

impl XmlType for HistoryUpdateType

const TAG: &'static str = "HistoryUpdateType"

The static fallback tag for this type. Convenience feature, but also used in nested types.

fn tag(&self) -> &str

The XML tag name for this type.

impl Copy for HistoryUpdateType

impl Eq for HistoryUpdateType

impl StructuralPartialEq for HistoryUpdateType
