Errors that can occur during SBF parsing

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidSync

Invalid sync bytes (expected 0x24 0x40)

CrcMismatch

CRC checksum mismatch

Fields

expected: u16

actual: u16

IncompleteBlock

Block is incomplete (not enough data)

Fields

needed: usize

have: usize

InvalidLength(u16)

Invalid block length (must be >= 8 and divisible by 4)

ParseError(String)

Block-specific parsing error

Io(Error)

I/O error during reading

WouldBlock

No complete block is available yet, but the stream has not ended.

Returned by SbfReader::read_block when a non-blocking source (for example a serial port in non-blocking mode) has no data available right now. This is distinct from end of stream: EOF is reported as Ok(None), whereas WouldBlock means the caller should retry later. Blocking sources (files, Cursor) never produce this.

Trait Implementations

impl Debug for SbfError

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

Formats the value using the given formatter.

impl Display for SbfError

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

Formats the value using the given formatter.

impl Error for SbfError

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<Error> for SbfError

fn from(source: Error) -> Self

Converts to this type from the input type.
