Implementations

impl Altout

pub fn lock(&self) -> AltoutLock<'_>

The lock is released when the returned lock goes out of scope. The returned guard also provide write_fmt() for writing data.

pub fn write_fmt(&mut self, args: Arguments<'_>) -> Result<()>

Writes a formatted string into Altout, won’t returning any error.

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

No-op.

pub fn is_terminal(&self) -> bool

Returns false to indicate it isn’t a terminal/tty.

impl Altout

pub fn recv(&self) -> String

Receives text from altio output stream.

This function will always block the current thread if there is no data available.

pub fn try_recv(&self) -> Option<String>

Tries to receive text from altio output stream, without blocking.

pub fn recv_line(&self) -> String

Receives one line of text from altio output stream.

This function will always block the current thread if there is no data available.

pub fn try_recv_line(&self) -> Option<String>

Tries to receive one line of text from altio output stream, without blocking.

pub fn recv_lines(&self, cnt: usize) -> String

Receives certain amount lines of text from altio output stream.

This function will always block the current thread if there is no data available.

pub fn try_recv_lines(&self, cnt: usize) -> Option<String>

Tries to receive certain amount lines of text from altio output stream.

pub fn peek_line(&self) -> Option<String>

Read one line of text in altio output stream, leaving it in the stream.

This function will always block the current thread if there is no data available.

pub fn peek_lines(&self, cnt: usize) -> Option<String>

Tries to receive certain amount lines of text in altio output stream, leaving it in the stream.

This function will always block the current thread if there is no data available.
