IOErr

NotFound - An entity was not found, often a file.

PermissionDenied - The operation lacked the necessary privileges to complete.

BrokenPipe - The operation failed because a pipe was closed.

AlreadyExists - An entity already exists, often a file.

Interrupted - This operation was interrupted. Interrupted operations can typically be retried.

Unsupported - This operation is unsupported on this platform. This means that the operation can never succeed.

OutOfMemory - An operation could not be completed, because it failed to allocate enough memory.

Other - A custom error that does not fall under any other I/O error kind.

line! : Str => Result {} [StdoutErr IOErr]

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

To write to stdout without the newline, see Stdout.write!.

write! : Str => Result {} [StdoutErr IOErr]

Write the given string to standard output.

Note that many 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 stdout with a newline at the end, see Stdout.line!.
