pub struct BoxFileReader { /* fields omitted */ }

Implementations

impl BoxFileReader

pub fn open_at_offset<P: AsRef<Path>>(
    path: P,
    offset: u64
) -> Result<BoxFileReader>

This will open an existing .box file for reading and writing, and error if the file is not valid.

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

This will open an existing .box file for reading and writing, and error if the file is not valid.

pub fn path(&self) -> &Path

pub fn alignment(&self) -> u64

pub fn version(&self) -> u32

pub fn metadata(&self) -> &BoxMetadata

pub fn decompress_value<V: Decompress>(&self, record: &FileRecord) -> Result<V>

pub fn decompress<W: Write>(&self, record: &FileRecord, dest: W) -> Result<()>

pub fn extract<P: AsRef<Path>>(
    &self,
    path: &BoxPath,
    output_path: P
) -> Result<()>

pub fn extract_all<P: AsRef<Path>>(&self, output_path: P) -> Result<()>

pub fn resolve_link(&self, link: &LinkRecord) -> Result<RecordsItem<'_>>

pub fn read_bytes(&self, record: &FileRecord) -> Result<Take<File>>

pub unsafe fn memory_map(&self, record: &FileRecord) -> Result<Mmap>

Safety

Use of memory maps is unsafe as modifications to the file could affect the operation of the application. Ensure that the Box being operated on is not mutated while a memory map is in use.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
