Stderr

Stderr :: # (opaque)

Write text or raw bytes to the process's standard error stream.

line! : Str => Try({}, [StderrErr(IOErr)])

Write the given string to standard error, followed by a newline.

To write to stderr without the newline, see [Stderr.write!].

write! : Str => Try({}, [StderrErr(IOErr)])

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, see [Stderr.line!].

write_bytes! : List(U8) => Try({}, [StderrErr(IOErr)])

Write the given bytes to standard error.

Most terminals will not actually display content that are written to them until they receive a newline, so this may appear to do nothing until you write a newline!
