Struct eosio::DataStream

pub struct DataStream { /* fields omitted */ }

A stream of bytes

Methods

impl DataStream

pub fn read<T: Read>(&mut self) -> Result<T, ReadError>

Read something from the stream

Errors

Will return Err if there was a problem reading the data.

pub fn write<T: Write>(&mut self, thing: T) -> Result<(), WriteError>

Write something to the stream

Errors

Will return Err if there was a problem writing the data.

#[must_use] pub fn as_bytes(&self) -> &[u8]

Gets the remaining number of bytes

#[must_use] pub fn as_remaining_bytes(&self) -> Option<&[u8]>

Gets remaining bytes as slice

pub fn reset(&mut self)

Resets the data stream position

#[must_use] pub const fn position(&self) -> usize

Get the current position

#[must_use] pub fn remaining(&self) -> usize

Gets the remaining number of bytes
