Error raised while lowering music to a MIDI file.

Variants

ZeroTpq

The target ticks-per-quarter resolution was zero.

PitchOutOfRange

A pitch fell outside the representable MIDI range.

VelocityOutOfRange

A note velocity fell outside the playable 1..=127 range.

Fields

velocity: u8

The offending velocity value.

ChannelOutOfRange

A note channel fell outside the 0..=15 range.

Fields

channel: u8

The offending channel value.

InexactTime

A duration could not be represented exactly at the target TPQ.

InvalidTempo

A tempo value was not positive and finite.

InvalidTimeSignature

A time-signature denominator was not a power of two.

UnsupportedPianoRollCell

A piano-roll cell had no SMF representation.

Fields

lane: String

The lane containing the unsupported cell.

cell_kind: String

The kind of the unsupported cell.

Smf(SmfError)

A serialization error surfaced from sim-lib-midi-smf.

Trait Implementations

impl Clone for LowerError

fn clone(&self) -> LowerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LowerError

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

Formats the value using the given formatter.

impl Display for LowerError

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

Formats the value using the given formatter.

impl Eq for LowerError

impl Error for LowerError

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<SmfError> for LowerError

fn from(source: SmfError) -> Self

Converts to this type from the input type.

impl PartialEq for LowerError

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

Equality operator ==.

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

Inequality operator !=.
