Struct Const

#[repr(transparent)]
pub struct Const<T, U>(pub T, _);

Same as RawConst<T, U> but holds U instead of T, i.e. holds the parsed value.

MyDeserialize::deserialize will error with io::ErrorKind::InvalidData if T::try_from(_: U::Primitive) fails.

Tuple Fields

0: T

Implementations

impl<T, U> Const<T, U>

pub fn new(t: T) -> Self

Creates a new Const.

Trait Implementations

impl<T: Clone, U: Clone> Clone for Const<T, U>

fn clone(&self) -> Const<T, U>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug, U: Debug> Debug for Const<T, U>

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

Formats the value using the given formatter.

impl<T: Default, U: Default> Default for Const<T, U>

fn default() -> Const<T, U>

Returns the “default value” for a type.

impl<T, U> Deref for Const<T, U>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T, U> DerefMut for Const<T, U>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: Hash, U: Hash> Hash for Const<T, U>

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<'de, T, U> MyDeserialize<'de> for Const<T, U>

where U: IntRepr, T: TryFrom<U::Primitive>, <T as TryFrom<U::Primitive>>::Error: Error + Send + Sync + 'static,

const SIZE: Option<usize> = U::SIZE

Size hint of a serialized value (in bytes), if it’s constant.

type Ctx = ()

Some structs defines deserialization in the context of another value.

fn deserialize((): Self::Ctx, buf: &mut ParseBuf<'de>) -> Result<Self>

Deserializes self from the given buf.

impl<T, U> MySerialize for Const<T, U>

where T: Copy + Into<U::Primitive>, U: IntRepr,

fn serialize(&self, buf: &mut Vec<u8>)

Serializes self into the buf.

impl<T: Ord, U: Ord> Ord for Const<T, U>

fn cmp(&self, other: &Const<T, U>) -> 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<T: PartialEq, U: PartialEq> PartialEq for Const<T, U>

fn eq(&self, other: &Const<T, U>) -> 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<T: PartialOrd, U: PartialOrd> PartialOrd for Const<T, U>

fn partial_cmp(&self, other: &Const<T, U>) -> 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.
