pub enum Output {
    Pipe,
    File(OsString, File),
}

Implementations

impl Output

pub fn new<S: AsRef<OsStr>>(path: S) -> Result<Self>

Contructs a new output either by opening/creating the file or for '-' returning stdout

pub fn try_from_os_str(path: &OsStr) -> Result<Self, OsString>

Contructs a new output either by opening/creating the file or for '-' returning stdout The error is converted to a OsString so that stuctopt can show it to the user

pub fn finish(mut self: Self) -> Result<()>

Syncs the file to disk or closes any HTTP connections and returns any errors or on the file if a regular file

Trait Implementations

impl Debug for Output

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

Formats the value using the given formatter.

impl Display for Output

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

Formats the value using the given formatter.

impl TryFrom<&'_ OsStr> for Output

type Error = OsString

The type returned in the event of a conversion error.

fn try_from(file_name: &OsStr) -> Result<Self, OsString>

Performs the conversion.

impl Write for Output

fn flush(&mut self) -> IoResult<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write(&mut self, buf: &[u8]) -> IoResult<usize>

Write a buffer into this writer, returning how many bytes were written.

pub fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

pub fn is_write_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

pub fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

pub fn write_all_vectored(
    &mut self,
    bufs: &mut [IoSlice<'_>]
) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

pub fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

pub fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Write.
