Struct CallData

pub struct CallData { /* private fields */ }

The raw ABI respecting input data to a call.

Note

The first four bytes are the function selector and the rest are SCALE encoded inputs.

Implementations

impl CallData

pub fn new(selector: Selector) -> Self

Creates new call ABI data for the given selector.

pub fn push_arg<A>(&mut self, arg: &A)

where A: Encode,

Pushes the given argument onto the call ABI data in encoded form.

pub fn selector(&self) -> Selector

Returns the selector of self.

pub fn params(&self) -> &[u8]

Returns the underlying bytes of the encoded input parameters.

pub fn to_bytes(&self) -> &[u8]

Returns the underlying byte representation.

Trait Implementations

impl Clone for CallData

fn clone(&self) -> CallData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CallData

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

Formats the value using the given formatter.

impl Decode for CallData

fn decode<I: Input>(input: &mut I) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

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 Encode for CallData

fn size_hint(&self) -> usize

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

fn encode_to<T: Output + ?Sized>(&self, dest: &mut T)

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

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where 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 PartialEq for CallData

fn eq(&self, other: &CallData) -> 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.
