Errors raised while reading or writing a Standard MIDI File.

Variants

InvalidHeader

The MThd/MTrk chunk header was malformed.

Fields

offset: usize

Byte offset of the bad header.

UnexpectedEof

The byte stream ended before the structure was complete.

Fields

offset: usize

Byte offset where more input was expected.

InvalidVlq

A variable-length quantity was not terminated within four bytes.

Fields

offset: usize

Byte offset where the VLQ began.

UnsupportedSmpteDivision

The header requested SMPTE division, which is not supported.

Fields

offset: usize

Byte offset of the division field.

raw: u16

The raw division value.

MalformedRunningStatus

A data byte appeared with no running status in effect.

Fields

offset: usize

Byte offset of the offending data byte.

UnsupportedStatus

A status byte that the reader does not handle was encountered.

Fields

offset: usize

Byte offset of the status byte.

status: u8

The unsupported status byte.

InvalidChannelData

A channel message carried an out-of-range data byte.

Fields

offset: usize

Byte offset of the bad data.

FormatTrackMismatch

The header format and the track count are inconsistent (for example, format 0 with more than one track).

InexactEventTime

An event time could not be represented exactly at the file resolution.

NegativeDelta

Track events were not monotonic in absolute time, yielding a negative delta.

Trait Implementations

impl Clone for SmfError

fn clone(&self) -> SmfError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SmfError

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

Formats the value using the given formatter.

impl Display for SmfError

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

Formats the value using the given formatter.

impl Eq for SmfError

impl Error for SmfError

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 SmfError

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