Struct ink_env::call::Selector

pub struct Selector { /* fields omitted */ }

The function selector.

Implementations

impl Selector

pub const fn new(bytes: [u8; 4]) -> Self

Creates a selector directly from 4 bytes.

pub const fn to_bytes(self) -> [u8; 4]

Returns the underlying bytes of the selector.

Trait Implementations

impl Clone for Selector

fn clone(&self) -> Selector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Selector

impl Debug for Selector

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

Formats the value using the given formatter.

impl Decode for Selector

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

Attempt to deserialise the value from input.

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

Attempt to skip the encoded value from input.

pub fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for Selector

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

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: FnOnce(&[u8]) -> R>(&self, f: F) -> R

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

pub fn size_hint(&self) -> usize

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

pub fn encoded_size(&self) -> usize

Calculates the encoded size.

impl EncodeLike<Selector> for Selector

impl Eq for Selector

impl From<[u8; 4]> for Selector

fn from(original: [u8; 4]) -> Selector

Performs the conversion.

impl PartialEq<Selector> for Selector

fn eq(&self, other: &Selector) -> bool

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

fn ne(&self, other: &Selector) -> bool

This method tests for !=.
