Crate gstuff

Modules

• oneshot
  Reason for having this is that neither multiqueue nor crossbeam_channel implement UnwindSafe currently.

Macros

• ERR
  Returns a Err(String), prepending the current location (file name and line number) to the string.
• ERRL
  Prepends file name and line number to the given message.
• gstring
  A helper to build a string on the stack.
• try_f
  Returns on error, prepending the current location to a stringified error, then passing the string to From::from.
• try_fu
  Lifts an error into a boxed future. Box<Future<Item=_, Error=_>>.
• try_fus
  Lifts an error into a boxed future. Box<Future<Item=_, Error=String>>.
• try_s
  Returns on error, converting the Err value to String and prepending the current location.
• try_sp
  Like try_s, but takes a reference.

Structs

• FileLock
  Allows several threads or processes to compete for a shared resource by tracking resource ownership with a file.
  If the lock file is older than ttl_sec then it is removed, allowing us to recover from a thread or process dying while holding the lock.
• OrdFloat
  Allows to sort by float, but panics if there’s a NaN or infinity
• ProcEn
  Process entry in /proc.
• ProcIt
  Iterate over processes in /proc.

Functions

• any_to_str
  Useful with panic handlers.
• bedstead2bits
  Bedstead to row-major bits, 2x3
• binprint
  Helps logging binary data (particularly with text-readable parts, such as bencode, netstring) by replacing all the non-printable bytes with the blank character.
• bits2bedstead
  Row-major bits, 2x3, to Bedstead
• cmd
  Run a command, printing it first. Stdout and stderr are forwarded through (inherit).
• duration_to_float
  Converts the duration into a number of seconds with fractions.
• duration_to_ms
  Converts the duration into a number of milliseconds.
• filename
  Shortcut to path->filename conversion.
• last_modified_sec
  Last-modified of the file in seconds since the UNIX epoch, with fractions.
  Returns 0 if the file does not exists.
• ms2sec
  Converts time in milliseconds into a number of seconds with fractions.
• netstring
  Takes a netstring from the front of the slice.
• now_float
  The current number of seconds since UNIX epoch, with fractions.
• now_ms
  The current number of milliseconds since UNIX epoch.
• round_to
• slurp
  Read contents of the file into a Vec.
• slurp_prog
  Runs a command in a shell, returning stderr+stdout on success.
• with_hostname
  Wraps gethostname to fetch the current hostname into a temporary buffer.
