Struct DirUploader 

pub struct DirUploader { /* private fields */ }

Writes each upload into one directory as {uuid}-{basename} and stores its URL under url_prefix; Panel::uploads_dir installs it and serves the directory there.

Panel::new("admin")
    .uploads(DirUploader::new("/uploads", "var/uploads"))
    .serve_dir("/uploads/{*file}", "var/uploads");

Implementations

impl DirUploader

pub fn new(url_prefix: impl Into<String>, dir: impl Into<PathBuf>) -> Self

Writes into dir, naming each file by a URL under url_prefix ("/uploads").

pub fn expire_pending(self, age: Duration) -> Self

Marks each file it stores pending until the panel’s write that stores it commits, and deletes a pending file once it is age old: the upload of a submission that never saved, such as a refused form the user left. Panel::uploads_dir sets 24 hours.

A store sweeps at most once an hour. Only the panel’s record forms keep what they store: an app page that stores through this uploader and saves the path itself keeps it with Uploader::keep, or uses an uploader without this setting.

Trait Implementations

impl Clone for DirUploader

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DirUploader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Uploader for DirUploader

async fn holds(&self, path: &str) -> bool

Whether the directory holds the file a URL store returned names. The name store writes is the check, since the directory keeps no index of what it wrote: a file whose name it would not write is not held.

async fn keep(&self, path: &str) -> Result<(), String>

Drops the pending mark of the file a URL store returned names.

async fn delete(&self, path: &str) -> Result<(), String>

Removes the file a URL store returned names, and its pending mark; a file already gone is no error.

async fn store(&self, filename: &str, bytes: &[u8]) -> Result<String, String>

Stores bytes and returns the value to store; the Err string renders inside the field’s inline error, so it must be user-actionable.
