pub struct PdfReader<'a> { /* private fields */ }

A byte-level reader over a PDF byte slice, with position tracking.

Implementations

impl<'a> PdfReader<'a>

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

pub fn new_at(data: &'a [u8], pos: usize) -> Self

Create a reader starting at a specific offset.

pub fn pos(&self) -> usize

Current byte offset in the data.

pub fn len(&self) -> usize

Total length of the underlying data.

pub fn is_empty(&self) -> bool

Whether the underlying data is empty.

pub fn is_eof(&self) -> bool

Whether we’ve reached the end.

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

Peek at the current byte without consuming.

pub fn peek_at(&self, n: usize) -> Option<u8>

Peek at the byte at offset pos + n.

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

Consume and return the current byte.

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

Advance position by n bytes.

pub fn seek(&mut self, pos: usize)

Set position to an absolute offset.

pub fn slice(&self, start: usize, end: usize) -> &'a [u8]

Return a slice from the underlying data.

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

Return remaining bytes from current position.

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

The full underlying data.

pub fn skip_whitespace(&mut self)

Skip PDF whitespace characters: \0, \t, \n, \x0C, \r, \x20.

pub fn skip_whitespace_and_comments(&mut self)

Skip whitespace and comments (% to end of line).
