Struct ConstCode

pub struct ConstCode<const CODE: usize>;

A zero-sized struct with a const generic parameter representing a code using the values exported by the code_consts module.

Methods for all traits are implemented for this struct using a match on the value of the const type parameter. Since the parameter is a constant, the match is resolved at compile time, so there will be no runtime overhead.

If the value is not among those defined in the code_consts module, the methods will panic.

See the module documentation for more information.

Implementations

impl<const CODE: usize> ConstCode<CODE>

pub fn read<E: Endianness, CR: CodesRead<E> + ?Sized>( &self, reader: &mut CR, ) -> Result<u64, CR::Error>

Delegate the read method to the DynamicCodeRead implementation.

This inherent method is provided to reduce ambiguity in method resolution.

pub fn write<E: Endianness, CW: CodesWrite<E> + ?Sized>( &self, writer: &mut CW, value: u64, ) -> Result<usize, CW::Error>

Delegate to the DynamicCodeWrite implementation.

This inherent method is provided to reduce ambiguity in method resolution.

Trait Implementations

impl<const CODE: usize> Clone for ConstCode<CODE>

fn clone(&self) -> ConstCode<CODE>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const CODE: usize> CodeLen for ConstCode<CODE>

fn len(&self, value: u64) -> usize

Return the length of the codeword for value.

impl<const CODE: usize> CopyType for ConstCode<CODE>

type Copy = False

impl<const CODE: usize> Debug for ConstCode<CODE>

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

Formats the value using the given formatter.

impl<const CODE: usize> DynamicCodeRead for ConstCode<CODE>

fn read<E: Endianness, CR: CodesRead<E> + ?Sized>( &self, reader: &mut CR, ) -> Result<u64, CR::Error>

impl<const CODE: usize> DynamicCodeWrite for ConstCode<CODE>

fn write<E: Endianness, CW: CodesWrite<E> + ?Sized>( &self, writer: &mut CW, value: u64, ) -> Result<usize, CW::Error>

impl<const CODE: usize> MemDbgImpl for ConstCode<CODE>

fn _mem_dbg_rec_on( &self, _memdbg_writer: &mut impl Write, _memdbg_total_size: usize, _memdbg_max_depth: usize, _memdbg_prefix: &mut String, _memdbg_is_last: bool, _memdbg_flags: DbgFlags, ) -> Result

fn _mem_dbg_depth_on( &self, writer: &mut impl Write, total_size: usize, max_depth: usize, prefix: &mut String, field_name: Option<&str>, is_last: bool, padded_size: usize, flags: DbgFlags, ) -> Result<(), Error>

impl<const CODE: usize> MemSize for ConstCode<CODE>

fn mem_size(&self, _memsize_flags: SizeFlags) -> usize

Returns the (recursively computed) overall memory size of the structure in bytes.

impl<const CODE: usize> PartialEq for ConstCode<CODE>

fn eq(&self, other: &ConstCode<CODE>) -> 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.
