Struct devlog::path::LogPath[][src]

pub struct LogPath { /* fields omitted */ }


impl LogPath[src]

Devlog entry files are numbered sequentially, starting from one. Each filename is nine digits with the extension “.devlog”; for example, “000000123.devlog”. This ensures that the devlog files appear in sequential order when sorted alphabetically.

pub fn new(dir: &Path, seq_num: usize) -> LogPath[src]

Create a new path with the specified sequence number, which must be at least one and at most MAX_SEQ_NUM.

pub fn from_path(path: PathBuf) -> Option<LogPath>[src]

Parse the sequence number from a filesystem path. Returns None if the filename isn’t formatted like “000000123.devlog”.

pub fn next(&self) -> Result<LogPath, Error>[src]

Returns the path for the next entry in the sequence. In the unlikely event that the maximum sequence number is reached, returns Error::LogFileLimitExceeded.

pub fn seq_num(&self) -> usize[src]

Returns the sequence number (e.g. “00000123.devlog” would have sequence number 123)

pub fn path(&self) -> &Path[src]

Returns the filesystem path.
