Struct imap_types::core::NonEmptyVec

pub struct NonEmptyVec<T>(_);

A Vec that always contains >= 1 elements.

Some messages in IMAP require a list of at least one element. We encoded these situations in a non-empty vector type to not produce invalid messages.

The Debug implementation equals Vec with an attached + at the end.

Implementations

impl<T> NonEmptyVec<T>

pub fn validate(value: &[T]) -> Result<(), NonEmptyVecError>

pub fn unvalidated(inner: Vec<T>) -> Self

Available on crate feature unvalidated only.

Constructs a non-empty vector without validation.

Warning: IMAP conformance

The caller must ensure that inner is valid according to Self::validate. Failing to do so may create invalid/unparsable IMAP messages, or even produce unintended protocol flows. Do not call this constructor with untrusted data.

pub fn into_inner(self) -> Vec<T>

Trait Implementations

impl<'a, T> Arbitrary<'a> for NonEmptyVec<T>where T: Arbitrary<'a>,

fn arbitrary(u: &mut Unstructured<'a>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl<T> AsRef<[T]> for NonEmptyVec<T>

fn as_ref(&self) -> &[T]

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Clone> Clone for NonEmptyVec<T>

fn clone(&self) -> NonEmptyVec<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for NonEmptyVec<T>where T: Debug,

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for NonEmptyVec<T>where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<T> for NonEmptyVec<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for NonEmptyVec<T>

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<T: IntoBoundedStatic> IntoBoundedStatic for NonEmptyVec<T>

type Static = NonEmptyVec<<T as IntoBoundedStatic>::Static>

The target type is bounded by the 'static lifetime.

fn into_static(self) -> Self::Static

Convert an owned T into an owned T such that T: 'static.

impl<T> IntoIterator for NonEmptyVec<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<<NonEmptyVec<T> as IntoIterator>::Item, Global>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T: PartialEq> PartialEq<NonEmptyVec<T>> for NonEmptyVec<T>

fn eq(&self, other: &NonEmptyVec<T>) -> 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<T> Serialize for NonEmptyVec<T>where T: Serialize,

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

Serialize this value into the given Serde serializer.

type Static = NonEmptyVec<<T as ToBoundedStatic>::Static>

The target type is bounded by the 'static lifetime.

fn to_static(&self) -> Self::Static

Convert an &T to an owned T such that T: 'static.

impl<T> TryFrom<Vec<T, Global>> for NonEmptyVec<T>

type Error = NonEmptyVecError

The type returned in the event of a conversion error.

fn try_from(inner: Vec<T>) -> Result<Self, Self::Error>

Performs the conversion.
