Struct YcdIndexEntry 

pub struct YcdIndexEntry {
    pub path: PathBuf,
    pub data_offset: u64,
    pub file_start: usize,
    pub file_length: usize,
    pub file_size: u64,
    pub modified: SystemTime,
}

One entry in a YcdIndex, representing a single YCD file.

The snapshot fields (file_size, modified) are recorded at index-build time and compared against the filesystem when a file is actually read. Any mismatch causes read_digits to return an explicit “stale index” error rather than silently reading potentially incorrect data.

Fields

path: PathBuf

Absolute path to the YCD file.

data_offset: u64

Byte offset at which compressed 8-byte blocks start.

file_start: usize

1-based absolute digit position of this file’s first digit.

file_length: usize

Total number of digits stored in this file.

file_size: u64

File size in bytes recorded at index-build time.

modified: SystemTime

Last-modified time recorded at index-build time.

On platforms where std::fs::Metadata::modified() is unavailable, this field is set to SystemTime::UNIX_EPOCH at build time and read_digits will also read UNIX_EPOCH for the current mtime, so the comparison will always succeed. On those platforms stale-index detection relies solely on file_size.
