Stderr
Err
BrokenPipe - This error can occur when writing to a stdout that is no longer connected to a valid input. For example, if the process on the receiving end of a pipe closes its end, any write to that pipe could lead to a BrokenPipe error.
WouldBlock - This error might occur if stdout is set to non-blocking mode and the write operation would block because the output buffer is full.
WriteZero - This indicates an attempt to write "zero" bytes which is technically a no-operation (no-op), but if detected, it could be raised as an error.
Unsupported - If the stdout operation involves writing data in a manner or format that is not supported, this error could be raised.
Interrupted - This can happen if a signal interrupts the writing process before it completes.
OutOfMemory - This could occur if there is not enough memory available to buffer the data being written to stdout.
Other - This is a catch-all for any error not specifically categorized by the other ErrorKind variants.
line : Str -> Task {} [StderrErr Err]
Write the given string to standard error, followed by a newline.
To write to
stderr
without the newline, seeStderr.write
.
write : Str -> Task {} [StderrErr Err]
Write the given string to standard error.
Most terminals will not actually display strings that are written to them until they receive a newline, so this may appear to do nothing until you write a newline!
To write to
stderr
with a newline at the end, seeStderr.line
