Struct light_cli::LightCliOutput

pub struct LightCliOutput<'a, E: 'a> { /* fields omitted */ }

Methods

impl<'a, E> LightCliOutput<'a, E>

pub fn new(writer: &'a mut dyn Write<u8, Error = E>) -> Self

Creates a now buffered console output instance.

Arguments

• writer: The serial output instance, implementing the Write<u8> interface.

pub fn flush(&mut self) -> Result<(), E>

Tries to send as many characters as it can until the interface starts blocking or there are no charactors to submit.

Remarks

If the function returns Ok, then the buffer has succesfully been flushed whereas the error WouldBlock indicates that it is not empty but would have blocked if it tried to submit the character.

To completely empty the buffer, use block!(cl_output.flush()).unwrap().

Trait Implementations

impl<'a, E> Write for LightCliOutput<'a, E>

fn write_str(&mut self, s: &str) -> Result

Writes a slice of bytes into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a [char] into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments) -> Result<(), Error>

Glue for usage of the [write!] macro with implementors of this trait.
