Struct UploadCleanup 

pub struct UploadCleanup {
    pub uploaded_paths: Vec<ExerciseServiceUploadCleanup>,
    file_store: Data<dyn FileStore>,
    armed: bool,
}

Deletes the objects an upload has already stored, unless the upload got far enough to disarm it.

Objects reach the store before their rows are committed, so an upload that fails part way has to delete them itself; the reaper only finds objects through the rows that were never written. On the handler’s own error path call clean_up and await it. The Drop path is the backstop for the case that has no error path at all: the client aborting the multipart body, which drops the handler future at an await point.

Fields

uploaded_paths: Vec<ExerciseServiceUploadCleanup>

file_store: Data<dyn FileStore>

armed: bool

Implementations

impl UploadCleanup

pub fn new(file_store: Data<dyn FileStore>) -> Self

pub async fn clean_up(&mut self)

Deletes what has been stored so far and disarms, so the Drop backstop cannot delete the same objects again.

pub fn disarm(&mut self)

Call only once the uploads are recorded, with no await in between: an await would give the runtime a chance to drop the handler and delete objects that already have rows.

Trait Implementations

impl Drop for UploadCleanup

fn drop(&mut self)

Executes the destructor for this type.
