Struct BufReader 

pub struct BufReader<'r> { /* private fields */ }

A reader for TXS-encoded XDR data from a byte slice.

This reader implements the Reader trait for the TXS (Traditional XDR Serialization) format. It reads data from a byte slice and tracks the current position.

Implementations

impl<'a> BufReader<'a>

pub fn new(data: &'a [u8]) -> Self

Creates a new BufReader that reads from the given byte slice.

The reader starts at position 0.

pub fn position(&self) -> usize

Returns the current read position in the buffer.

pub fn remaining(&self) -> usize

Returns the number of bytes remaining to be read.

pub fn remaining_slice(&self) -> &'a [u8]

Returns a slice of the remaining unread bytes.

Trait Implementations

impl<'r> Reader<'r> for BufReader<'r>

fn read_opaque_fixed(&mut self, len: usize) -> ReadResult<&'r [u8]>

Reads a byte array of known length, borrowing the contents from the reader.

fn read_opaque_variable(&mut self, max: u32) -> ReadResult<&'r [u8]>

Reads a byte sequence of variable length (not exceeding max), borrowing the contents from the reader.

fn read_i16(&mut self) -> ReadResult<i16>

Reads a signed 16-bit integer.

fn read_u16(&mut self) -> ReadResult<u16>

Reads an unsigned 16-bit integer.

fn read_u64(&mut self) -> ReadResult<u64>

Reads an unsigned 64-bit integer.

fn read_u32(&mut self) -> ReadResult<u32>

Reads an unsigned 32-bit integer.

fn read_i64(&mut self) -> ReadResult<i64>

Reads a signed 64-bit integer.

fn read_i32(&mut self) -> ReadResult<i32>

Reads a signed 32-bit integer.

fn read_f32(&mut self) -> ReadResult<f32>

Reads a 32-bit IEEE 754 floating-point value.

fn read_f64(&mut self) -> ReadResult<f64>

Reads a 64-bit IEEE 754 floating-point value.

fn read_bool(&mut self) -> ReadResult<bool>

Reads a boolean value.

fn read_opaque_fixed_into<'a>( &mut self, dst: &'a mut [MU<u8>], len: u32, ) -> ReadResult<&'a mut [u8]>

Reads a byte array of known length, copying into a provided buffer rather than borrowing from the reader.

fn read_opaque_variable_into<'a>( &mut self, dst: &'a mut [MU<u8>], max: u32, ) -> ReadResult<&'a mut [u8]>

Reads a byte sequence of variable length, copying into a provided buffer. rather than borrowing from the reader.

fn read_opaque_fixed_owned(&mut self, len: u32) -> ReadResult<Vec<u8>>

Available on crate feature alloc only.

Reads a byte array of known length, returning an owned Vec<u8>.

fn read_opaque_variable_owned(&mut self, max: u32) -> ReadResult<Vec<u8>>

Available on crate feature alloc only.

Reads a byte sequence of variable length, returning an owned Vec<u8>.
