Struct Ask 

pub struct Ask<R, W> { /* private fields */ }

The default: shows the warning and waits for the word yes.

The streams are whatever the caller hands over, which in the binary means stdin and stderr rather than the controlling terminal. Two consequences worth knowing rather than discovering: git-xcrypt lock < answers.txt proceeds if the first line is yes, and git-xcrypt lock 2>/dev/null waits on a prompt nobody can see. Opening /dev/tty instead would fix both on Unix and has no portable equivalent, and this binary ships on Windows too.

Implementations

impl<R: BufRead, W: Write> Ask<R, W>

pub const fn new(input: R, output: W) -> Self

Asks on output and reads the answer from input.

Trait Implementations

impl<R: BufRead, W: Write> Confirm for Ask<R, W>

fn confirm(&mut self, warning: &Warning) -> Result<bool>

Accepts the exact word yes and nothing else.

Not y, not YES: the founding document asks for a word typed in full because the point of the prompt is to interrupt a reflex. End of input — a run with no terminal behind it, lock < /dev/null in a script — reads as a refusal, which is the direction that changes nothing.

impl<R: Debug, W: Debug> Debug for Ask<R, W>

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

Formats the value using the given formatter.
