Expand description

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

Implementations

source

impl Opts

source

pub fn new(args: I) -> Result<Self>where
I: IntoIterator<Item = String>,

source

pub fn iflag(&self, flag: In) -> bool

iflag returns true if the specified iflag is set

let mut o = opts::Opts::default();
o.iflags = flags::In::APPEND | flags::In::SYNC;
assert!(o.iflag(flags::In::APPEND));
assert!(!o.iflag(flags::In::NOFOLLOW));
