Creates a value from an iterator. Read more
source§

impl<T> PartialEq for MultiValueVec<T>
where T: PartialEq,

source§

fn eq(&self, other: &MultiValueVec<T>) -> bool

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

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> TopDecodeMulti for MultiValueVec<T>
where T: TopDecodeMulti,

source§

fn multi_decode_or_handle_err<I, H>( input: &mut I, h: H ) -> Result<MultiValueVec<T>, <H as DecodeErrorHandler>::HandledErr>

source§

const IS_SINGLE_VALUE: bool = false

Used to optimize single value loading of endpoint arguments.
source§

fn multi_decode<I>(input: &mut I) -> Result<Self, DecodeError>

source§

impl<T> TopEncodeMulti for MultiValueVec<T>
where T: TopEncodeMulti,

source§

fn multi_encode_or_handle_err<O, H>( &self, output: &mut O, h: H ) -> Result<(), <H as EncodeErrorHandler>::HandledErr>

Version of top_encode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.
source§

fn multi_encode<O>(&self, output: &mut O) -> Result<(), EncodeError>

Attempt to serialize the value to ouput.
source§

impl<T: TypeAbi> TypeAbi for MultiValueVec<T>

source§

fn type_name() -> TypeName

source§

fn provide_type_descriptions<TDC: TypeDescriptionContainer>( accumulator: &mut TDC )

A type can provide more than its own name. For instance, a struct can also provide the descriptions of the type of its fields. TypeAbi doesn’t care for the exact accumulator type, which is abstracted by the TypeDescriptionContainer trait.
