Struct tectonic_io_base::OutputHandle

pub struct OutputHandle { /* fields omitted */ }

A handle for Tectonic output streams.

Implementations

impl OutputHandle

pub fn new<T: 'static + Write>(name: &OsStr, inner: T) -> OutputHandle

Create a new output handle.

pub fn name(&self) -> &OsStr

Get the name associated with this handle.

pub fn into_inner(self) -> Box<dyn Write>

Consumes the object and returns the underlying writable handle that it references.

pub fn into_name_digest(self) -> (OsString, DigestData)

Consumes the object and returns the SHA256 sum of the content that was written.

Trait Implementations

impl Write for OutputHandle

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

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

pub fn flush(&mut self) -> Result<()>

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

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.
