Struct multiversx_sc::types::heap::ArgBuffer

pub struct ArgBuffer { /* private fields */ }

Helper structure for providing arguments to all SC call functions other than async_call_raw. It keeps argument lengths separately from the argument data itself. Argument data is concatenated into a single byte buffer.

Implementations

impl ArgBuffer

pub fn new() -> Self

pub fn push_argument_bytes(&mut self, arg_bytes: &[u8])

pub fn num_args(&self) -> usize

pub fn arg_lengths_bytes_ptr(&self) -> *const u8

pub fn arg_data_ptr(&self) -> *const u8

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

returns the raw arg data

pub fn arg_lengths(&self) -> &[usize]

returns the raw arg data lengths

pub fn for_each_arg<F: FnMut(&[u8])>(&self, f: F)

Quick for-each using closures. TODO: also write an Iterator at some point, but beware of wasm bloat.

pub fn is_empty(&self) -> bool

pub fn concat(self, other: ArgBuffer) -> Self

Concatenates 2 ArgBuffer. Consumes both arguments in the process.

Trait Implementations

impl Clone for ArgBuffer

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for ArgBuffer

fn default() -> Self

Returns the “default value” for a type.

impl From<&[BoxedBytes]> for ArgBuffer

fn from(raw_args: &[BoxedBytes]) -> Self

Converts to this type from the input type.

impl<M> From<&ArgBuffer> for ManagedArgBuffer<M>

where M: ManagedTypeApi,

fn from(arg_buffer: &ArgBuffer) -> Self

Converts to this type from the input type.

impl<M> From<&ManagedArgBuffer<M>> for ArgBuffer

where M: ManagedTypeApi + 'static,

fn from(managed_arg_buffer: &ManagedArgBuffer<M>) -> Self

Converts to this type from the input type.

impl<M> From<ArgBuffer> for ManagedArgBuffer<M>

where M: ManagedTypeApi,

fn from(arg_buffer: ArgBuffer) -> Self

Converts to this type from the input type.

impl TopEncodeOutput for &mut ArgBuffer

type NestedBuffer = Vec<u8>

Type of NestedEncodeOutput that can be spawned to gather serializations of children.

fn set_slice_u8(self, bytes: &[u8])

fn start_nested_encode(&self) -> Self::NestedBuffer

fn finalize_nested_encode(self, nb: Self::NestedBuffer)

fn set_u64(self, value: u64)

fn set_i64(self, value: i64)

fn supports_specialized_type<T>() -> bool

where T: TryStaticCast,

fn set_specialized<T, H>( self, _value: &T, h: H ) -> Result<(), <H as EncodeErrorHandler>::HandledErr>

where T: TryStaticCast, H: EncodeErrorHandler,

Allows special handling of special types. Also requires an alternative serialization, in case the special handling is not covered. The alternative serialization, else_serialization is only called when necessary and is normally compiled out via monomorphization.
