Struct Headless

Source

pub struct Headless<D: Document> { /* private fields */ }

Expand description

A session of an app without a window: what the CLI, MCP and tests drive. Implements Dispatch; effects that need a window are dropped (toasts are logged).

Implementations§

Source §

pub fn registry(&self) -> &Registry<Session<D>>

The command table (built-ins and the app’s).

Source

pub fn dirs(&self) -> Option<&AppDirs>

Where the app keeps its files.

Source

pub fn name(&self) -> &str

Source

pub fn default_dir(&self) -> Option<PathBuf>

Where an untitled document of this app would be saved by default.

where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
