Struct MappedFileReader 

pub struct MappedFileReader { /* private fields */ }

A memory-mapped file reader.

Uses memmap2 to efficiently access file contents without loading the entire file into memory.

Implementations

impl MappedFileReader

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self>

Opens a file for memory-mapped reading.

Errors

Returns an error if the file cannot be opened or memory-mapped.

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

Returns the file contents as a byte slice.

pub fn len(&self) -> usize

Returns the file size in bytes.

pub fn is_empty(&self) -> bool

Returns true if the file is empty.

pub fn chunks(&self) -> impl Iterator<Item = &[u8]>

Returns an iterator over 8-byte chunks.

Each chunk corresponds to a raw TPX3 packet.
