Struct StreamMap 

pub struct StreamMap {
    pub block_first_file_index: Vec<usize>,
    pub file_block_index: Vec<Option<usize>>,
    /* private fields */
}

Mapping structure that correlates files, blocks, and pack streams within an archive.

This structure maintains the relationships between archive entries and their corresponding compression blocks and packed data streams.

Fields

block_first_file_index: Vec<usize>

Index of first file for each block.

file_block_index: Vec<Option<usize>>

Block index for each file (None if file has no data).

Implementations

impl StreamMap

pub fn block_first_pack_stream_index(&self) -> &[usize]

Returns the index of the first pack stream for each block. Used for mapping blocks to their packed data streams.

pub fn pack_stream_offsets(&self) -> &[u64]

Returns byte offsets of each pack stream within the packed data region. Combined with pack_pos and SIGNATURE_HEADER_SIZE to get absolute offsets.

Trait Implementations

impl Clone for StreamMap

fn clone(&self) -> StreamMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamMap

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

Formats the value using the given formatter.

impl Default for StreamMap

fn default() -> StreamMap

Returns the “default value” for a type.
