Struct StudioFiles 

pub struct StudioFiles<S> { /* private fields */ }

The Studio’s files: the shipped examples over the reader’s store.

Implementations

impl<S> StudioFiles<S>

pub fn new(store: S) -> Self

pub fn store(&self) -> &S

The reader’s store underneath.

impl<S: Vfs> StudioFiles<S>

pub async fn retire_old_copies(&self) -> VfsResult<usize>

Remove the copies of the examples an earlier Studio wrote into the reader’s store, every file and folder under /examples, and count what went. They have not shown since the examples came from the site, and nothing else writes there, since the reader’s files live in /workspace. A store with no such folder costs one listing. A removal cut short finishes on the next visit.

Trait Implementations

impl<S: Clone> Clone for StudioFiles<S>

fn clone(&self) -> StudioFiles<S>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S: Vfs> Vfs for StudioFiles<S>

fn read<'a, 'b, 'f>( &'a self, path: &'b str, ) -> Pin<Box<dyn Future<Output = VfsResult<Vec<u8>>> + Send + 'f>>

where Self: 'f, 'a: 'f, 'b: 'f,

Read entire file contents as bytes.

fn read_to_string<'a, 'b, 'f>( &'a self, path: &'b str, ) -> Pin<Box<dyn Future<Output = VfsResult<String>> + Send + 'f>>

where Self: 'f, 'a: 'f, 'b: 'f,

Check if file exists.

fn remove<'a, 'b, 'f>( &'a self, path: &'b str, ) -> Pin<Box<dyn Future<Output = VfsResult<()>> + Send + 'f>>

where Self: 'f, 'a: 'f, 'b: 'f,

Delete a file.

fn create_dir_all<'a, 'b, 'f>( &'a self, path: &'b str, ) -> Pin<Box<dyn Future<Output = VfsResult<()>> + Send + 'f>>

where Self: 'f, 'a: 'f, 'b: 'f,

List entries in a directory.
