Struct SessionConfig 

pub struct SessionConfig {
    pub theme: Option<ThemeName>,
    pub editor: Option<PartialEditorConfig>,
    pub buffer_overrides: HashMap<PathBuf, PartialEditorConfig>,
}

Session-specific configuration for runtime/volatile overrides.

This struct represents the session layer of the config hierarchy - settings that are temporary and may not persist across editor restarts.

Unlike PartialConfig, SessionConfig provides a focused API for common runtime modifications like temporary theme switching.

Fields

theme: Option<ThemeName>

Temporarily override the theme (e.g., for preview)

editor: Option<PartialEditorConfig>

Temporary editor overrides (e.g., changing tab_size for current session)

buffer_overrides: HashMap<PathBuf, PartialEditorConfig>

Buffer-specific overrides keyed by absolute file path. These allow per-file settings that persist only during the session.

Implementations

impl SessionConfig

pub fn new() -> Self

Create a new empty session config.

pub fn set_theme(&mut self, theme: ThemeName)

Set a temporary theme override.

pub fn clear_theme(&mut self)

Clear the theme override, reverting to lower layers.

pub fn set_editor_option<F>(&mut self, setter: F)

where F: FnOnce(&mut PartialEditorConfig),

Set an editor setting for the current session.

pub fn set_buffer_override( &mut self, path: PathBuf, config: PartialEditorConfig, )

Set a buffer-specific editor override.

pub fn clear_buffer_override(&mut self, path: &Path)

Clear buffer-specific overrides for a path.

pub fn get_buffer_override(&self, path: &Path) -> Option<&PartialEditorConfig>

Get buffer-specific editor config if set.

pub fn to_partial_config(&self) -> PartialConfig

Convert to a PartialConfig for merging with other layers.

pub fn is_empty(&self) -> bool

Check if this session config has any values set.
