Struct RawConst

#[repr(transparent)]
pub struct RawConst<T: IntRepr, U>(pub T::Primitive, _);

Wrapper for a raw value of a MySql constant, enum variant or flags value.

• T – specifies the raw value,
• U – specifies the parsed value.

Tuple Fields

0: T::Primitive

Implementations

impl<T: IntRepr, U> RawConst<T, U>

impl<T: Default + IntRepr, U: Default> Default for RawConst<T, U>

where T::Primitive: Default,

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: IntRepr, U> DerefMut for RawConst<T, U>

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

Mutably dereferences the value.

impl<T: Hash + IntRepr, U: Hash> Hash for RawConst<T, U>

where T::Primitive: Hash,

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: IntRepr, U> MyDeserialize<'de> for RawConst<T, U>

const SIZE: Option<usize> = T::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: IntRepr, U> MySerialize for RawConst<T, U>

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

Serializes self into the buf.

impl<T: Ord + IntRepr, U: Ord> Ord for RawConst<T, U>

where T::Primitive: Ord,

fn cmp(&self, other: &RawConst<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 + IntRepr, U: PartialEq> PartialEq for RawConst<T, U>

where T::Primitive: PartialEq,

fn eq(&self, other: &RawConst<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 + IntRepr, U: PartialOrd> PartialOrd for RawConst<T, U>

where T::Primitive: PartialOrd,

fn partial_cmp(&self, other: &RawConst<T, U>) -> Option<Ordering>

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.
