}

The parsed and handled user options.

Fields

cflags: Conv

convert the file as per the comma separated symbol list

iflags: In

handle the input as per the comma-separated symbol list (see flags::In)

oflags: Out

handle the output as per the comma-separated symbol list (see flags::Out)

mode: Mode

The main mode to run in. Can be Mode::Standard, Mode::Block(usize), Mode::Unblock(usize)

count: Option<usize>

The limit in bytes or blocks to read

files: Option<usize>

Copy n input files before terminating. This operand is only applicable when the input device is a tape.

input_block_size: usize

The block size of the input, in bytes. Default is 512.

input_file: Option<String>

The input file, if any. input_file == None -> stdin

input_seek: Option<usize>

How many input_block_sized blocks to seek on the input. If also flags::In::SEEK_BYTES, seek that many bytes instead

output_block_size: usize

The block size of the output, in bytes. Default is 512.

output_file: Option<String>

The output file, if any. output_file == None -> stdout

output_seek: Option<usize>

How many output_block_sized blocks to seek on the output file. Incompatible with output_file==None

status: StatusLevel

Trait Implementations

impl Clone for Opts

fn clone(&self) -> Opts

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Opts

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

Formats the value using the given formatter.

impl Default for Opts

fn default() -> Opts

Returns the “default value” for a type.

impl Unimplemented for Opts

const KIND: Kind = Kind::BasicOption

Kind of option; used for reporting errors

const UNIMPLEMENTED: &'static [&'static str] = _

Slice of valid but as yet unimplemented options

fn check_if_implemented(flag: &str) -> Result<()>

check if a flag is valid but unimplemented

fn unknown<T>(flag: String) -> Result<T>

helper function; an invalid flag key
