Struct WChar 

pub struct WChar(pub char);

IDL wchar wrapper for the CORBA/GIOP 1.2 wire form. Holds a single Unicode scalar (char), but unlike the DDS XCDR2 wchar (a bare 2-byte UTF-16 code unit, no prefix) the GIOP 1.2 form is a 1-octet length (the octet count of the wchar in the transmission code set — 2 for a BMP character in UTF-16) followed by the UTF-16 code unit(s).

Byte order: the code units are emitted big-endian regardless of the message byte order. This is the consensus oracle-confirmed behaviour of both omniORB 4.3 (writes 02 00 41 for 'A' even inside a little-endian encapsulation) and JacORB 3.9 (02 00 41, big-endian message). The default UTF-16 transmission wide code set has no per-wchar BOM, so network (big-endian) order is used. wchar 'A' (U+0041) = 02 0041.

A CORBA wchar is a single transmission unit: real ORBs (omniORB CORBA::WChar, Java char) are 16-bit, so only BMP characters occur (length 2, one unit). A non-BMP scalar would need a UTF-16 surrogate pair (length 4, two units); the encoder handles that defensively even though the ORBs cannot produce it through write_wchar.

Implementations

impl WChar

pub fn as_char(&self) -> char

The inner Unicode scalar.

Trait Implementations

impl CdrDecode for WChar

fn decode(reader: &mut BufferReader<'_>) -> Result<Self, DecodeError>

Reads this value from the reader (alignment-aware).

const IS_PRIMITIVE: bool = false

XCDR2 primitive classification, symmetric to CdrEncode::IS_PRIMITIVE. Controls DHEADER reading when decoding sequence<T>/T[N] with non-primitive T.

impl CdrEncode for WChar

fn encode(&self, writer: &mut BufferWriter) -> Result<(), EncodeError>

Writes this value into the writer (alignment-aware).

const IS_PRIMITIVE: bool = false

XCDR2 primitive classification (OMG XTypes 1.3 §7.4.3.5): true only for primitives (bool, octet, int8/16/32/64, uint8/16/32/64, float, double, char/wchar). false for aggregate/variable types (string, struct, union, enum, sequence, array, map). Controls DHEADER prepending for sequence<T>/T[N]: collections with NON-primitive elements need a DHEADER (uint32 = byte length of the following content) under XCDR2.

impl Clone for WChar

fn clone(&self) -> WChar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for WChar

impl Debug for WChar

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

Formats the value using the given formatter.

impl Default for WChar

fn default() -> WChar

Returns the “default value” for a type.

impl Eq for WChar

impl From<char> for WChar

fn from(c: char) -> Self

Converts to this type from the input type.

impl Hash for WChar

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for WChar

fn cmp(&self, other: &WChar) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for WChar

fn eq(&self, other: &WChar) -> 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 PartialOrd for WChar

fn partial_cmp(&self, other: &WChar) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
