Function is_terminal::is_terminal 
source · pub fn is_terminal<T: IsTerminal>(this: T) -> boolExpand description
Returns true if this is a terminal.
This is equivalent to calling this.is_terminal() and exists only as a
convenience to calling the trait method IsTerminal::is_terminal
without importing the trait.
Example
if is_terminal::is_terminal(&std::io::stdout()) {
    println!("stdout is a terminal")
}
