}

An LTC codeword parse / serialize error.

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.

BufferTooShort

Input (on parse) or output buffer (on serialize) shorter than the fixed 10-byte (80-bit) LTC codeword.

Fields

need: usize

Bytes required.

have: usize

Bytes available.

what: &'static str

What was being parsed/serialized.

SyncWordMismatch

Bits 64–79 did not match the fixed synchronization word (§9.2.5, Table 5: bytes 0xFC 0xBF under this crate’s bit-to-byte packing — see docs/st12-1.md’s “Byte packing convention” section).

Fields

expected: [u8; 2]

The fixed sync word bytes (see crate::SYNC_WORD).

found: [u8; 2]

The bytes actually found at positions 8/9 (bits 64–79).

InvalidValue

A time-address field (hours/minutes/seconds/frames) exceeded its valid range (§5.2/§6.2/§7.2, §9.2.1 Table 2).

Fields

field: &'static str

The offending field name.

value: u8

The offending value.

reason: &'static str

Why it is invalid.

InvalidBinaryGroup

One of the eight 4-bit binary groups (“user bits”, §8.1/Table 4) held a value outside 0x0..=0xF.

Fields

index: usize

The binary group’s index, 0..8 (first..eighth, Table 4 order).

value: u8

The offending value.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
