Struct FileNameProps 

pub struct FileNameProps { /* private fields */ }

Metadata history files’ filename contains. The filename can be precisely restored from it.

Implementations

impl FileNameProps

pub fn new( control: u32, prev_ctl: u32, order: Vec<u32>, tag: Option<String>, ) -> Result<FileNameProps, FsError>

Create item from metadata.

pub fn from(filename: &str) -> Option<FileNameProps>

pub fn control(&self) -> u32

how many times “start_new” is called or deriving has happened.

pub fn prev_ctl(&self) -> u32

If this item is derived, “control” of the parent item, otherwise this item’s “control”

pub fn order(&self) -> &[u32]

numbers which describes how this item is derived. if the order is [3,8,2], this item depends on items which has the order of [3] and [3,8]

order.len >= 1

pub fn phase(&self) -> usize

self.order.len() - 1

pub fn order_base(&self) -> &[u32]

the last item of the order is excluded panics if the order.len() == 0

pub fn tag(&self) -> Option<&str>

string data users can append in this item’s filename.

pub fn calc_filename(&self) -> String

calculate the filename from the metadata this item contains.

Trait Implementations

impl Clone for FileNameProps

fn clone(&self) -> FileNameProps

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileNameProps

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

Formats the value using the given formatter.

impl PartialEq for FileNameProps

fn eq(&self, other: &FileNameProps) -> 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.
