Struct MultiValueVec

pub struct MultiValueVec<T>(pub Vec<T>);

Structure that allows taking a variable number of arguments or returning a variable number of results in a smart contract endpoint.

Tuple Fields

0: Vec<T>

Trait Implementations

impl<T> Clone for MultiValueVec<T>

where T: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for MultiValueVec<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for MultiValueVec<T>

where T: Default,

fn default() -> MultiValueVec<T>

Returns the “default value” for a type.

impl<T, const N: usize> From<[T; N]> for MultiValueVec<T>

where T: Clone,

fn from(arr: [T; N]) -> MultiValueVec<T>

Converts to this type from the input type.

impl<T> From<Vec<T>> for MultiValueVec<T>

fn from(v: Vec<T>) -> MultiValueVec<T>

Converts to this type from the input type.

impl<T> FromIterator<T> for MultiValueVec<T>

fn from_iter<I>(iter: I) -> MultiValueVec<T>

where I: IntoIterator<Item = T>,

Creates a value from an iterator.

impl<T> PartialEq for MultiValueVec<T>

where T: PartialEq,

fn eq(&self, other: &MultiValueVec<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> TopDecodeMulti for MultiValueVec<T>

where T: TopDecodeMulti,

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

where I: TopDecodeMultiInput, H: DecodeErrorHandler,

const IS_SINGLE_VALUE: bool = false

Used to optimize single value loading of endpoint arguments.

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

where I: TopDecodeMultiInput,

impl<T> TopEncodeMulti for MultiValueVec<T>

where T: TopEncodeMulti,

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

where O: TopEncodeMultiOutput, H: EncodeErrorHandler,

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.

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

where O: TopEncodeMultiOutput,

Attempt to serialize the value to ouput.

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

type Unmanaged = MultiValueVec<<T as TypeAbi>::Unmanaged>

fn type_name() -> TypeName

fn type_name_rust() -> TypeName

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.

fn type_names() -> TypeNames

impl<T> Eq for MultiValueVec<T>

where T: Eq,
