Struct randselect::Args

pub struct Args {
    pub in_dir: PathBuf,
    pub out_dir: PathBuf,
    pub num_files: usize,
    pub move_files: bool,
    pub go: bool,
    pub seed: Option<u64>,
}

Fields

in_dir: PathBuf

The input directory to select from.

out_dir: PathBuf

The directory to output to. Will be created if it doesn't exist.

num_files: usize

The number of files to select.

move_files: bool

Whether to move the files from IN_DIR to OUT_DIR, rather than cp.

go: bool

Execute the copy or move. Specify a seed for deterministic behavior.

seed: Option<u64>

The seed to use for the PRNG (u64).

Trait Implementations

impl Debug for Args

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

Formats the value using the given formatter.

impl StructOpt for Args

pub fn clap<'a, 'b>() -> App<'a, 'b>

Returns clap::App corresponding to the struct.

pub fn from_clap(matches: &ArgMatches<'_>) -> Self

Builds the struct from clap::ArgMatches. It's guaranteed to succeed if matches originates from an App generated by StructOpt::clap called on the same type, otherwise it must panic.

pub fn from_args() -> Self

Builds the struct from the command line arguments (std::env::args_os). Calls clap::Error::exit on failure, printing the error message and aborting the program.

pub fn from_args_safe() -> Result<Self, Error>

Builds the struct from the command line arguments (std::env::args_os). Unlike StructOpt::from_args, returns clap::Error on failure instead of aborting the program, so calling .exit is up to you.

pub fn from_iter<I>(iter: I) -> Self where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

pub fn from_iter_safe<I>(iter: I) -> Result<Self, Error> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making.

impl StructOptInternal for Args

pub fn augment_clap<'a, 'b>(app: App<'a, 'b>) -> App<'a, 'b>

pub fn is_subcommand() -> bool

pub fn from_subcommand(
    _sub: (&'b str, Option<&'b ArgMatches<'a>>)
) -> Option<Self>
