Enum SaveState 

pub enum SaveState {
    Clean,
    Dirty,
    Saving,
    Failed {
        reason: SharedString,
    },
}

Whether what a tab holds has been written down, and what happened when somebody tried.

The three unclean variants are separate presentations, not one “modified” flag with a colour. A save that failed silently and then showed a clean tab would tell the typist their work is safe when it is not, which is the exact failure this library exists to avoid — so SaveState::Failed carries the host’s own reason and the tab publishes itself as invalid.

Variants

Clean

Everything in this tab is written down.

Dirty

There are changes nobody has written down yet.

Saving

A save is in flight. Not clean: it has not landed.

Failed

A save was attempted and did not land, in the host’s own words.

Fields

reason: SharedString

Implementations

impl SaveState

pub fn name(&self) -> &'static str

The name the semantic tree publishes, so a test tells the three apart without reading a colour.

pub fn is_clean(&self) -> bool
