Struct DefaultPayload 

pub struct DefaultPayload<ArgsData, ReturnTy> { /* private fields */ }

A View Function payload containing the generic argument data and interpreting the result of the call as ReturnTy.

This can be created from static values (ie those generated via the subxt macro) or dynamic values via dynamic.

Implementations

impl<ReturnTy, ArgsData> DefaultPayload<ArgsData, ReturnTy>

pub fn new(query_id: [u8; 32], args_data: ArgsData) -> Self

Create a new DefaultPayload for a View Function call.

pub fn unvalidated(self) -> Self

Do not validate this call prior to submitting it.

pub fn args_data(&self) -> &ArgsData

Returns the arguments data.

Trait Implementations

impl<ArgsData, ReturnTy> Clone for DefaultPayload<ArgsData, ReturnTy>

where ArgsData: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<ArgsData, ReturnTy> Debug for DefaultPayload<ArgsData, ReturnTy>

where ArgsData: Debug,

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

Formats the value using the given formatter.

impl<ArgsData, ReturnTy> Ord for DefaultPayload<ArgsData, ReturnTy>

where ArgsData: Ord,

fn cmp(&self, __other: &Self) -> 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,

Restrict a value to a certain interval.

impl<ArgsData, ReturnTy> PartialEq for DefaultPayload<ArgsData, ReturnTy>

where ArgsData: PartialEq,

fn eq(&self, __other: &Self) -> 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<ArgsData, ReturnTy> PartialOrd for DefaultPayload<ArgsData, ReturnTy>

where ArgsData: PartialOrd,

fn partial_cmp(&self, __other: &Self) -> 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.

impl<ArgsData: EncodeAsFields, ReturnTy: DecodeWithMetadata> Payload for DefaultPayload<ArgsData, ReturnTy>

type ReturnType = ReturnTy

The return type of the function call.

fn query_id(&self) -> &[u8; 32]

The payload target.

fn encode_args_to( &self, metadata: &Metadata, out: &mut Vec<u8>, ) -> Result<(), Error>

Scale encode the arguments data.

fn validation_hash(&self) -> Option<[u8; 32]>

Returns the statically generated validation hash.

fn encode_args(&self, metadata: &Metadata) -> Result<Vec<u8>, Error>

Encode arguments data and return the output. This is a convenience wrapper around Payload::encode_args_to.

impl<ArgsData, ReturnTy> Eq for DefaultPayload<ArgsData, ReturnTy>

where ArgsData: Eq,
