Struct Attachment

pub struct Attachment {
    pub matched: usize,
    pub moved: usize,

    pub waiting_folders: BTreeMap<String, usize>,

What became of a batch of records handed to merge_into.

Fields

matched: usize

Records whose path the catalog already knew.

moved: usize

Records attached to a file that has moved since it was analysed.

stale: usize

Records about bytes that have changed since, and therefore dropped.

waiting: usize

Records kept although no file matches them yet.

older: usize

Incoming records superseded by a more recent result for the same file and source. Re-reading an old report must not undo a newer analysis.

waiting_folders: BTreeMap<String, usize>

The first few waiting folders, each with how many wait in it, for a report that names rather than counts.

Folders, not paths, and for the reason a reader would give: what one does with a waiting record is scan the folder it names, or decide that folder is gone. The file name inside it settles nothing, and listing every file of an album spends ten rows to say one thing. It also survives the column width — a path cut to fit is cut at the tail, where the file name is, leaving the head that identifies the folder exactly where it cannot be read.

stale_folders: BTreeMap<String, usize>

The first few folders holding a record dropped as stale, each with how many, for the same reason waiting_folders names rather than counts: “some files changed” answers how many, not which, and which is the one thing a reader needs to know where to point FlacCompagnon again.

Implementations

impl Attachment

pub fn attached(&self) -> usize

Records that found their file, one way or the other.

Trait Implementations

impl Clone for Attachment

fn clone(&self) -> Attachment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attachment

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

Formats the value using the given formatter.

impl Default for Attachment

fn default() -> Attachment

Returns the “default value” for a type.

impl PartialEq for Attachment

fn eq(&self, other: &Attachment) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
