Struct ArchiveReader 

pub struct ArchiveReader { /* private fields */ }

Reader for CASC archive files with memory mapping support

Implementations

impl ArchiveReader

pub fn can_memory_map(size: u64) -> bool

Determine if we can memory map a file of this size

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

Open an archive file for reading

pub fn reader_at( &self, offset: u64, length: usize, ) -> Result<ArchiveSection<'_>>

Create a reader at a specific offset for streaming access (zero-copy when possible)

pub fn read_at_cow(&self, offset: u64, length: usize) -> Result<Cow<'_, [u8]>>

Read data at a specific offset (returns Cow for zero-copy when possible)

pub fn read_at(&mut self, offset: u64, length: usize) -> Result<Vec<u8>>

Read data at a specific offset (allocates for compatibility)

pub fn read_slice(&self, offset: u64, length: usize) -> Result<&[u8]>

Read a slice of data without allocation (only works with mmap)

pub fn size(&self) -> u64

Get the size of the archive

pub fn is_memory_mapped(&self) -> bool

Check if memory mapping is available

pub fn prefetch(&self, offset: u64, length: usize) -> Result<()>

Prefetch data into memory (hint to OS)
