Struct Required

pub struct Required<V, const TAG: u64>(pub V);

A required CBOR tag

This data type indicates that the specified tag, and only that tag, is required during deserialization. If the tag is missing, deserialization will fail. The tag will always be emitted during serialization.

Trait Implementations

impl<V: Clone, const TAG: u64> Clone for Required<V, TAG>

fn clone(&self) -> Required<V, TAG>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V: Debug, const TAG: u64> Debug for Required<V, TAG>

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

Formats the value using the given formatter.

impl<'de, V: Deserialize<'de>, const TAG: u64> Deserialize<'de> for Required<V, TAG>

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl<V: Hash, const TAG: u64> Hash for Required<V, TAG>

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<V: Ord, const TAG: u64> Ord for Required<V, TAG>

fn cmp(&self, other: &Required<V, TAG>) -> 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<V: PartialEq, const TAG: u64> PartialEq for Required<V, TAG>

fn eq(&self, other: &Required<V, TAG>) -> 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<V: PartialOrd, const TAG: u64> PartialOrd for Required<V, TAG>

fn partial_cmp(&self, other: &Required<V, TAG>) -> 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.

impl<V: Serialize, const TAG: u64> Serialize for Required<V, TAG>

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl<V: Copy, const TAG: u64> Copy for Required<V, TAG>

impl<V: Eq, const TAG: u64> Eq for Required<V, TAG>

impl<V, const TAG: u64> StructuralPartialEq for Required<V, TAG>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
