Enum FileError 

pub enum FileError {
    OpenBusy,
    OpenFail,
    IoError,
    NoOpenFile,
    SessionTimeout,
    SessionFatalError,
    SessionOutOfSync {
        expected: u8,
        got: u8,
    },
    CompressionUnsupported,
    ProtocolViolation {
        state: &'static str,
        expected: &'static str,
    },
}

Reasons a transfer failed.

Variants

OpenBusy

Device replied PFT:busy to OPEN — another transfer is in progress on the device side.

OpenFail

Device replied PFT:fail to OPEN — likely SD card not present or write-protected.

IoError

Device replied PFT:ioerror to CLOSE.

NoOpenFile

Device replied PFT:invalid to CLOSE — no file was open.

SessionTimeout

The session emitted a Event::Timeout while we were waiting for a reply.

SessionFatalError

The session emitted a Event::FatalError.

SessionOutOfSync

The session emitted Event::OutOfSync.

Fields

expected: u8

Sync number we expected.

got: u8

Sync number the device acked.

CompressionUnsupported

Caller requested Compression::Heatshrink but the device only advertises none.

ProtocolViolation

Device sent the closing ok<n> for a CLOSE or ABORT without first emitting the expected PFT:* preamble. Without that preamble, the transfer can’t be classified as success or failure, so we surface the violation rather than silently claiming completion.

Fields

state: &'static str

Symbolic name of the FileTransfer state at the time of the ack.

expected: &'static str

The PFT preamble line(s) the protocol requires before the ack.

Trait Implementations

impl Clone for FileError

fn clone(&self) -> FileError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileError

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

Formats the value using the given formatter.

impl Display for FileError

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

Formats the value using the given formatter.

impl Error for FileError

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<FileError> for UploadError

Available on (crate features blocking or tokio or serial) and (crate features blocking or tokio) only.

fn from(source: FileError) -> Self

Converts to this type from the input type.

impl PartialEq for FileError

fn eq(&self, other: &FileError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
