Enum vector_config::schema::SingleOrVec

pub enum SingleOrVec<T> {
    Single(Box<T>),
    Vec(Vec<T>),
}

A type which can be serialized as a single item, or multiple items.

In some contexts, a Single may be semantically distinct from a Vec containing only item.

Variants

Single(Box<T>)

Vec(Vec<T>)

Implementations

impl<T> SingleOrVec<T>

where T: PartialEq,

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl<T> From<T> for SingleOrVec<T>

fn from(single: T) -> SingleOrVec<T>

Converts to this type from the input type.

impl<T> From<Vec<T>> for SingleOrVec<T>

fn from(vec: Vec<T>) -> SingleOrVec<T>

Converts to this type from the input type.

impl<'a, T> IntoIterator for &'a SingleOrVec<T>

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = Iter<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a SingleOrVec<T> as IntoIterator>::IntoIter

Creates an iterator from a value.

impl<T> Ord for SingleOrVec<T>

where T: Ord,

fn cmp(&self, other: &SingleOrVec<T>) -> 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 + PartialOrd,

impl<T> PartialEq for SingleOrVec<T>

where T: PartialEq,

fn eq(&self, other: &SingleOrVec<T>) -> 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 for SingleOrVec<T>

where T: PartialOrd,

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

where T: Serialize,

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
