Struct widgetry::tools::FileLoader

pub struct FileLoader<A, T> {
    path: String,
    on_load: Option<Box<dyn FnOnce(&mut EventCtx<'_>, &mut A, &mut Timer<'_>, Result<T>) -> Transition<A>>>,
}

Loads a JSON, bincoded, or raw file, then deserializes it

Fields

path: String

on_load: Option<Box<dyn FnOnce(&mut EventCtx<'_>, &mut A, &mut Timer<'_>, Result<T>) -> Transition<A>>>

Implementations

impl<A: 'static, T: 'static + Readable> FileLoader<A, T>

pub fn new_state( _: &mut EventCtx<'_>, path: String, on_load: Box<dyn FnOnce(&mut EventCtx<'_>, &mut A, &mut Timer<'_>, Result<T>) -> Transition<A>> ) -> Box<dyn State<A>>

Trait Implementations

impl<A: 'static, T: 'static + Readable> State<A> for FileLoader<A, T>

fn event(&mut self, ctx: &mut EventCtx<'_>, app: &mut A) -> Transition<A>

Respond to a UI event, such as input or time passing.

fn draw(&self, g: &mut GfxCtx<'_>, _: &A)

Draw

fn draw_baselayer(&self) -> DrawBaselayer

Specifies what to draw before draw()

fn on_destroy(&mut self, _: &mut EventCtx<'_>, _: &mut A)

Before this state is popped or replaced, call this.

fn recreate(&mut self, _: &mut EventCtx<'_>, _: &mut A) -> Box<dyn State<A>>

Respond to Transition::Recreate by assuming state in the app has changed, but preserving the State-specific state appropriately.
