Struct UploadError 

pub struct UploadError {
    pub source: Error,
    pub partial: Option<ObjectHandle>,
}

Error from a high-level upload, carrying the handle of the object the device created during the first phase before the data phase failed.

Uploads are two-phase: the object is created (returning a handle), then the bytes are streamed. If the data phase fails or is cancelled, the device may keep a partial (empty or truncated) object. This surfaces that handle so the caller owns the cleanup-or-resume decision; the library never auto-deletes it. (Backends differ: the WPD backend commits atomically, so partial is None there.)

[From<UploadError> for Error] keeps ? ergonomic; callers drop partial unless they match on UploadError explicitly.

Fields

source: Error

The underlying failure.

partial: Option<ObjectHandle>

The handle of the partially-written object the device may still hold, if any.

Trait Implementations

impl Debug for UploadError

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

Formats the value using the given formatter.

impl Display for UploadError

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

Formats the value using the given formatter.

impl Error for UploadError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
