Struct console::Term [] [src]

pub struct Term { /* fields omitted */ }

Abstraction around a terminal.

Methods

impl Term
[src]

Return a new unbuffered terminal

Return a new unbuffered terminal to stderr

Return a new buffered terminal

Return a new buffered terminal to stderr

Writes a string to the terminal and adds a newline.

Read a single character from the terminal

This does not echo the character and blocks until a single character is entered.

Read a single key form the terminal.

This does not echo anything. If the terminal is not user attended the return value will always be the unknown key.

Read one line of input.

This does not include the trailing newline. If the terminal is not user attended the return value will always be an empty string.

Read securely a line of input.

This is similar to read_line but will not echo the output. This also switches the terminal into a different mode where not all characters might be accepted.

Flushes internal buffers.

This forces the contents of the internal buffer to be written to the terminal. This is unnecessary for unbuffered terminals which will automatically flush.

Checks if the terminal is indeed a terminal.

Alternatively you can use the user_attended function which does the same.

Checks if this terminal wants emoji output.

Returns the terminal size or gets sensible defaults.

Returns the terminal size in rows and columns.

If the size cannot be reliably determined None is returned.

Moves the cursor up n lines

Moves the cursor down n lines

Clears the current line.

The positions the cursor at the beginning of the line again.

Clear the last n lines.

This positions the cursor at the beginning of the first line that was cleared.
