Trait Implementations

impl<K: Clone, V: Clone> Clone for IndexedVec<K, V>

fn clone(&self) -> IndexedVec<K, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K, V> Debug for IndexedVec<K, V>where K: Debug, V: Debug,

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

Formats the value using the given formatter.

impl<K, V> Decode for IndexedVec<K, V>where Vec<V>: Decode, PhantomData<fn(_: K) -> K>: Decode,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<K, V> Default for IndexedVec<K, V>

fn default() -> Self

Returns the “default value” for a type.

impl<K, V> Encode for IndexedVec<K, V>where Vec<V>: Encode, PhantomData<fn(_: K) -> K>: Encode,

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<K, V> From<Vec<V, Global>> for IndexedVec<K, V>

fn from(validators: Vec<V>) -> Self

Converts to this type from the input type.

impl<K, V> FromIterator<V> for IndexedVec<K, V>

fn from_iter<T: IntoIterator<Item = V>>(iter: T) -> Self

Creates a value from an iterator.

impl<K: PartialEq, V: PartialEq> PartialEq<IndexedVec<K, V>> for IndexedVec<K, V>

fn eq(&self, other: &IndexedVec<K, V>) -> 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.
