Reader

Struct Reader 

Source
pub struct Reader<'a> { /* private fields */ }
Expand description

Sequential reader for parsing FDT data structures.

Reader provides sequential read access with position tracking for parsing FDT binary format. It maintains a current position and can backtrack if needed.

§Examples

let mut reader = bytes.reader();
let value = reader.read_u32()?;
let str = reader.read_cstr()?;

Implementations§

Source§

impl<'a> Reader<'a>

Source

pub fn position(&self) -> usize

Returns the current read position in the original data.

Source

pub fn remain(&self) -> Bytes<'a>

Returns the remaining unread data as a Bytes.

Source

pub fn read_bytes(&mut self, size: usize) -> Option<Bytes<'a>>

Reads the specified number of bytes, advancing the position.

Returns None if insufficient bytes remain.

Source

pub fn read_u32(&mut self) -> Option<u32>

Reads a big-endian u32 value.

Source

pub fn read_u64(&mut self) -> Option<u64>

Reads a big-endian u64 value (composed of two u32 values).

Source

pub fn read_cells(&mut self, cell_count: usize) -> Option<u64>

Reads a value composed of the specified number of cells.

Each cell is 4 bytes (a u32). The cells are combined into a u64 value.

Source

pub fn read_token(&mut self) -> Result<Token, FdtError>

Reads a token from the FDT structure block.

Source

pub fn backtrack(&mut self, size: usize)

Moves the read position back by the specified size.
