Struct SeriesScan 

pub struct SeriesScan {
    pub path: PathBuf,
    pub header: Option<String>,
    pub segments: Vec<Range<u64>>,
    pub complete_bytes: u64,
    pub file_bytes: u64,
    pub first_dropped_offset: Option<u64>,
    pub kept_after_dropped: bool,
}

Layout of a series.csv: its header, and the stretches of complete lines in order of their run ids.

Fields

path: PathBuf

Path of the scanned file.

header: Option<String>

Header line as written with its line ending, None for a file with no complete header.

segments: Vec<Range<u64>>

Byte ranges of the longest stretches of complete lines whose run ids never decrease, in file order.

complete_bytes: u64

Number of bytes up to the end of the file’s last complete line.

file_bytes: u64

Size in bytes of the file, 0 for a missing file.

first_dropped_offset: Option<u64>

Offset of the first complete line the scan’s rule left out.

kept_after_dropped: bool

Whether a line that the rule kept comes after a line that it left out.

Implementations

impl SeriesScan

pub fn read(path: &Path, keep: impl Fn(u64) -> bool) -> Result<Self, ReadError>

Scans the series.csv at path, marking each complete line that keep rejects by its run id as left out. A missing file has no header and no lines.

Errors

Returns ReadError when the file cannot be read, or a complete line does not start with a run id.
