Trait Implementations§

Source§

impl Debug for Vio

Source§

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more
Source§

impl Default for Vio

Source§

fn default() -> Vio

Returns the “default value” for a type. Read more
Source§

impl PartialEq for Vio

Source§

fn eq(&self, other: &Vio) -> bool

Tests for self and other values to be equal, and is used by ==.
1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
Source§

impl VirtualIo for Vio

Source§

fn print<S: Into<String>>(&mut self, message: S) -> &mut Self

Prints a message to the console. Is close to the print! macro with one difference: output is not buffered and is instead immediately flushed.
Source§

fn println<S: Into<String>>(&mut self, message: S) -> &mut Self

Prints a message to the console with a new line at the end. Is equivalent to the println! macro.
Source§

fn read_line(&mut self) -> String

Get user input from the console. The input ends when the user types a new line.
Source§

fn get_environment_var<S: Into<String>>( &self, variable: S, ) -> Result<String, VarError>

Get an environment variable. Is equivalent to std::env::var. Read more
Source§

fn get_environment_vars(&self) -> Vec<(String, String)>

Get an environment variables as a vector. Each item in the vector is a (key, value) tuple.
