Struct ciborium::tag::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) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

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

fn eq(&self, other: &Required<V, TAG>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method 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<Required<V, TAG>> 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

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method 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> StructuralEq for Required<V, TAG>

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