Errors that can occur when parsing SD card files.

Variants

FileTooSmall

The file is too small to contain the expected data.

Fields

expected: usize

Minimum expected size in bytes.

actual: usize

Actual size in bytes.

InvalidModelString

The .d75 file header contains an unrecognised model string.

Fields

found: String

The model string found in the header.

MissingBom

A UTF-16LE encoded file is missing the byte order mark (BOM).

InvalidUtf16Length

A UTF-16LE file contains an odd number of bytes (invalid encoding).

Fields

len: usize

The byte count, which must be even for UTF-16.

Utf16Decode

A UTF-16 code unit sequence could not be decoded.

Fields

detail: String

Human-readable detail about the decode failure.

ColumnCount

A TSV row has an unexpected number of columns.

Fields

line: usize

The 1-based line number in the file.

expected: usize

The expected number of columns.

actual: usize

The actual number of columns.

InvalidField

A required field in a TSV row is empty or invalid.

Fields

line: usize

The 1-based line number in the file.

column: String

The column name or index.

detail: String

Human-readable detail about the problem.

ChannelParse

A channel entry in the .d75 binary could not be parsed.

Fields

index: u16

The 0-based channel index.

detail: String

Human-readable detail about the parse failure.

InvalidWavHeader

A WAV file header is invalid or corrupt.

Fields

detail: String

Human-readable detail about the problem.

UnexpectedAudioFormat

A WAV file has a valid header but unexpected audio format (not matching TH-D75 spec: 16 kHz, 16-bit, mono).

Fields

sample_rate: u32

The sample rate found in the file.

bits_per_sample: u16

The bits per sample found in the file.

channels: u16

The channel count found in the file.

InvalidBmpHeader

A BMP file header is invalid or corrupt.

Fields

detail: String

Human-readable detail about the problem.

UnexpectedImageFormat

A BMP file has a valid header but unexpected image format (not matching TH-D75 spec: 240x180, 24-bit).

Fields

width: u32

The image width found in the file.

height: u32

The image height found in the file.

bits_per_pixel: u16

The bits per pixel found in the file.

Trait Implementations

impl Clone for SdCardError

fn clone(&self) -> SdCardError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SdCardError

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

Formats the value using the given formatter.

impl Display for SdCardError

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

Formats the value using the given formatter.

impl Error for SdCardError

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 SdCardError

fn eq(&self, other: &SdCardError) -> 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.
