//! SectorReader — trait for reading 2048-byte disc sectors.
//!
//! Implemented by DriveSession (SCSI) and IsoFile (file-backed).
//! Used by UDF parser, disc scanner, label parsers — anything that
//! reads sectors doesn't need to know where they come from.

/// Read 2048-byte sectors from a disc or disc image.

    /// Read `count` sectors starting at `lba` into `buf`.
    /// `buf` must be at least `count * 2048` bytes.
