Struct CodeSetContext 

pub struct CodeSetContext {
    pub char_data: u32,
    pub wchar_data: u32,
}

CONV_FRAME::CodeSetContext — selected transmission codesets.

Fields

char_data: u32

char_data — transmission codeset for char/string (TCSC).

wchar_data: u32

wchar_data — transmission codeset for wchar/wstring (TCSW).

Implementations

impl CodeSetContext

pub const fn new(char_data: u32, wchar_data: u32) -> Self

Constructor.

pub const fn default_pair() -> Self

ZeroDDS default pair: UTF-8 (char) + UTF-16 (wchar).

pub fn encode_encapsulation( &self, endianness: Endianness, ) -> GiopResult<Vec<u8>>

Encodes the body as a CDR encapsulation (byte-order octet + two unsigned long). With standard CDR alignment relative to the start of the encapsulation, char_data sits at offset 4 and wchar_data at offset 8.

Errors

Buffer write error.

pub fn decode_encapsulation(encap: &[u8]) -> GiopResult<Self>

Decodes a CodeSetContext encapsulation (byte-order octet + body).

Errors

Truncated/invalid endianness or buffer read error.

pub fn to_service_context( &self, endianness: Endianness, ) -> GiopResult<ServiceContext>

Builds the GIOP ServiceContext (context_id = IOP::CodeSets = 1).

Errors

Encapsulation write error.

pub fn from_service_context_list( list: &ServiceContextList, ) -> GiopResult<Option<Self>>

Looks up the CodeSets entry in a ServiceContextList and decodes it. Returns Ok(None) if no codeset context is present.

Errors

Decode error if the entry exists but is corrupt.

Trait Implementations

impl Clone for CodeSetContext

fn clone(&self) -> CodeSetContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CodeSetContext

impl Debug for CodeSetContext

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

Formats the value using the given formatter.

impl Default for CodeSetContext

fn default() -> Self

Returns the “default value” for a type.

impl Eq for CodeSetContext

impl PartialEq for CodeSetContext

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