Struct SessionState 

pub struct SessionState {
    pub last_root: Option<PathBuf>,
    pub left_width: Option<u32>,
    pub right_width: Option<u32>,
}

Small runtime state persisted between launches.

Fields

last_root: Option<PathBuf>

The most recently opened root directory, if any.

left_width: Option<u32>

Left dock width from the last interactive resize, if any. Overrides the configured [panel] width on the next launch.

right_width: Option<u32>

Right dock width from the last interactive resize, if any.

Implementations

impl SessionState

pub fn load() -> Self

Load state from the environment’s state file. Missing or broken files yield an empty default.

pub fn load_from_path(path: &Path) -> Self

Load state from an explicit path.

pub fn save(&self) -> Result<()>

Persist state to the environment’s state file, creating directories.

pub fn save_to_path(path: &Path, state: &Self) -> Result<()>

Persist state to an explicit path, creating parent directories.

Atomic: the serialized bytes are written to a sibling temp file first and then renamed over the target, so a crash mid-write can never leave a truncated state.toml behind (the old file stays intact until the swap).
