Struct BufferedReader 

pub struct BufferedReader { /* private fields */ }

A simple in-memory buffered reader over a byte slice.

Simulates buffered line reading for I/O processing within the elaborator.

Implementations

impl BufferedReader

pub fn new(data: Vec<u8>) -> Self

Create a new buffered reader with default capacity (8 KiB).

pub fn from_str(s: &str) -> Self

Create a buffered reader from a string.

pub fn read_byte(&mut self) -> Option<u8>

Read a single byte, or None if at end.

pub fn read_line(&mut self) -> Option<String>

Read the next line (up to and including \n).

Returns None when the buffer is exhausted.

pub fn read_to_string(&mut self) -> Result<String, IoError>

Read all remaining content as a string.

pub fn read_exact(&mut self, n: usize) -> Result<Vec<u8>, IoError>

Read exactly n bytes.

Returns an error if fewer than n bytes remain.

pub fn peek(&self) -> Option<u8>

Peek at the next byte without consuming it.

pub fn is_eof(&self) -> bool

Check if the reader is at end of data.

pub fn remaining(&self) -> usize

Return the number of bytes remaining.

pub fn reset(&mut self)

Reset the reader to the beginning.

pub fn skip(&mut self, n: usize)

Skip n bytes.

pub fn capacity(&self) -> usize

Return the buffer capacity.

pub fn lines(&mut self) -> Vec<String>

Collect all lines into a vector.
