Struct BlockMap 

pub struct BlockMap {
    pub files: Vec<BlockFile>,
    pub total_blocks: u32,
    pub slice_size: u64,
}

Maps between global slice indices and per-file slice positions.

Global indices run across the set’s files in the Main packet’s file order (falling back to File ID order if the Main packet listed none); this is the order the PAR2 input constants are assigned in.

Fields

files: Vec<BlockFile>

Files in global order.

total_blocks: u32

Total number of input slices across all files.

slice_size: u64

Slice size in bytes.

Implementations

impl BlockMap

pub fn new(file_set: &Par2FileSet) -> Self

Build the global slice map for a file set. Same as build_block_map.

pub fn global_to_file(&self, global_idx: usize) -> Option<SliceLocation<'_>>

Locate a global slice index: its file, byte offset and real length. None if the index is out of range.

pub fn global_index(&self, filename: &str, local_index: u32) -> Option<usize>

Global index of slice local_index of the file named filename.

pub fn file(&self, filename: &str) -> Option<&BlockFile>

The entry for the file named filename.

Trait Implementations

impl Clone for BlockMap

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockMap

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

Formats the value using the given formatter.
