Crate gstuff [−] [src]

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.
find_parse_replace_s	Uses nom to find all matches of the given `$submac` parser and replace them with the parser's evaluations.
gstring	A helper to build a string on the stack.
parse_replace_s	Uses nom to find all matches of the given `$submac` parser and replace them with the `$submac` results.
take_until_find_parse_s	`$starts` is an optional `Pattern` used to optimize the `$remainder` search.
take_until_parse_s	Implements the `/(?x) (.*?) (remainder)/` pattern: looks for remainder first, then returns a tuple with the prefix and the remainder.
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.

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.
ISATTY	True if the standard output is a terminal.
ProcEn	Process entry in /proc.
ProcIt	Iterate over processes in /proc.

any_to_str	Useful with panic handlers.
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.
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.
netstring	Takes a netstring from the front of the slice.
now_float	The current number of seconds since the UNIX epoch, with fractions.
rdtsc	Time Stamp Counter (number of cycles).
slurp	Read contents of the file into a `Vec`.
slurp_prog	Runs a command in a shell, returning stderr+stdout on success.
status_line	Clears the line to the right, prints the given text, moves the caret all the way to the left.
status_line_clear	Clears the status line ff stdout `isatty` and `status_line` isn't empty.
with_hostname	Wraps `gethostname` to fetch the current hostname into a temporary buffer.
with_status_line	Clear the status line, run the code, then restore the status line.
