Struct libpna::RegularEntry

pub struct RegularEntry<T = Vec<u8>> { /* private fields */ }

Entry that read from PNA archive.

Implementations

impl<T> RegularEntry<T>

pub fn header(&self) -> &EntryHeader

Information in the header of the entry.

pub fn metadata(&self) -> &Metadata

Metadata of the entry.

pub fn xattrs(&self) -> &[ExtendedAttribute]

Extended attributes of the entry.

pub fn extra_chunks(&self) -> &[RawChunk<T>]

Extra chunks.

pub fn with_metadata(self, metadata: Metadata) -> Self

Apply metadata to the entry.

Example

use libpna::{EntryBuilder, Metadata};

let mut entry = EntryBuilder::new_dir("dir_entry".into()).build()?;
entry.with_metadata(Metadata::new());

pub fn with_xattrs(self, xattrs: &[ExtendedAttribute]) -> Self

Apply extended attributes to the entry.

Example

use libpna::{EntryBuilder, ExtendedAttribute};

let mut entry = EntryBuilder::new_dir("dir_entry".into()).build()?;
entry.with_xattrs(&[ExtendedAttribute::new("key".into(), b"value".into())]);

impl<T: Clone> RegularEntry<T>

pub fn with_extra_chunks(self, chunks: &[RawChunk<T>]) -> Self

Apply extra chunks to the entry.

Example

use libpna::{ChunkType, EntryBuilder, RawChunk};

let mut entry = EntryBuilder::new_dir("dir_entry".into()).build()?;
entry.with_extra_chunks(&[RawChunk::from_data(
    ChunkType::private(*b"myTy").unwrap(),
    b"some data",
)]);

impl<T: AsRef<[u8]>> RegularEntry<T>

pub fn reader(&self, option: ReadOptions) -> Result<EntryDataReader<'_>>

Return the reader of this RegularEntry.

Examples

use libpna::{Archive, ReadOptions};
use std::{fs, io};

let file = fs::File::open("foo.pna")?;
let mut archive = Archive::read_header(file)?;
for entry in archive.entries_skip_solid() {
    let entry = entry?;
    let mut reader = entry.reader(ReadOptions::builder().build())?;
    let name = entry.header().path();
    let mut dist_file = fs::File::create(name)?;
    io::copy(&mut reader, &mut dist_file)?;
}

impl<T: Ord> Ord for RegularEntry<T>

fn cmp(&self, other: &RegularEntry<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl<T: PartialEq> PartialEq for RegularEntry<T>

fn eq(&self, other: &RegularEntry<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
