Struct SpoolReader 

pub struct SpoolReader { /* private fields */ }

Reads cards from a spool file

Implementations

impl SpoolReader

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

Open a spool file

pub fn open_embedded<P: AsRef<Path>>(path: P, base_offset: u64) -> Result<Self>

Open a spool embedded within a larger file at a given byte offset.

Reads the SP01 header starting at base_offset, then adjusts all internal offsets so that read_card() seeks to the correct position within the host file. This enables direct access to spool data stitched into an Engram archive without temp extraction.

pub fn card_count(&self) -> usize

Get number of cards in spool

pub fn read_card(&mut self, index: usize) -> Result<Vec<u8>>

Read a card by index

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

Read a card at specific offset and length

pub fn get_entry(&self, index: usize) -> Option<&SpoolEntry>

Get entry for a card index

pub fn entries(&self) -> &[SpoolEntry]

Get all entries
