Struct ErrHandler

pub struct ErrHandler<E: Write> { /* private fields */ }

ErrHandler handles errors, writing errors and/or perodic reports to the speicifed file or stderr. see StatusLevel and NOERROR ErrHandler handles errors and progress information by writing to it’s internal writer.

Implementations

impl<E: Write> ErrHandler<E>

pub fn new(e: E, o: &Opts) -> Self

impl<E: Write> ErrHandler<E>

pub const BLOCK_THRESHOLD_FOR_REPORT: usize = 25usize

threshold of blocks written per report.

pub const LINE_THRESHOLD_FOR_REPORT: usize = 20usize

threshold of lines written per report.

pub const STANDARD_BYTE_THRESHOLD: usize = 5_000_000usize

threshold of bytes written per erport

pub fn handle<T>(&mut self, res: Result<T>) -> Result<Option<T>>

handle an error, promoting it unless continue_on_error is set.

pub fn report_status_standard( &mut self, bytes: usize, start: &SystemTime, ) -> Result<()>

report status during standard operation

pub fn report_status_block(&mut self, lines: usize, start: &SystemTime)

pub fn report_status_unblock(&mut self, blocks: usize, start: &SystemTime)

Trait Implementations

impl<E: Write> Write for ErrHandler<E>

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

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

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

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

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

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

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.

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

Attempts to write an entire buffer into this writer.

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.

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

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

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

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
