Struct Notice 

pub struct Notice { /* private fields */ }

One sentence for the footer, and how long it stays there.

Why not a timer

A timer is the wrong answer for a report of what was destroyed. A reader who looked away while it counted down has no way to get it back, and the thing it described is not on disk any more — so the one state a countdown leaves them in is “something happened and nothing will say what”. Every lifetime here is therefore a reader’s action rather than a clock.

Two lifetimes, because the reports differ in what it costs to miss one

passing is an ordinary report — what was removed, what was priced, why a key did nothing. The next thing the reader does takes it away, because by then it describes the frame before rather than the one in front of them.

standing names something refused or failed. The safety model collects those and the run exits non-zero on them, so a sentence that says a directory was left alone or could not be removed is the only place a reader learns that from — and an arrow key pressed while reading it must not be what takes it away. Nothing incidental clears one: it goes when it is dismissed, or when a newer report answers a keystroke the reader has just made.

Both are dismissed by Esc and by a press on the footer, which is the rung View::step_back takes first.

Implementations

pub fn passing(said: impl Into<String>) -> Self

pub fn standing(said: impl Into<String>) -> Self

One that names something refused or failed, and so waits to be dismissed.

pub fn said(&self) -> &str

The sentence itself.

pub fn stands(&self) -> bool

Whether it waits to be dismissed rather than going with the reader’s next action.
