Structs

MaybePromptedString	MaybePromptedString is a wrapper for getting user input interactively, while also allowing the value to be specified at call time. This is useful e.g. when we want to prompt users interactively, but want to predefine the values in unit tests, or when users can specify a value either interactively or via flags.
TerminalAttributes	This is an opaque structure which encapsulates the state / attributes of an interactive terminal. The contents of this structure are OS-specific.

Stream	Standard input / output streams.
TerminalFlag	This enum describes high-level terminal flags, in an OS-agnostic way.

AbstractStream	This trait describes an abstract input or output stream.
AbstractTerminalAttributes	This trait describes an abstract type which describes the attributes of a terminal.

continue_confirmation	Display a " Continue?" confirmation. Returns true if the user replies "yes" (or similar), or false otherwise.
prompt_for_string	Prompt the user for a string (read from the given input stream) using the given output stream (typically standard output or standard error) to display the given prompt message.
prompt_for_string_confirm	Prompt for a string as per `prompt_for_string`, but additionally have the user enter the value again to confirm we get the same answer twice. This is useful for e.g. password entry.

An alias for std::io::Result.
