Enum TransformError 

pub enum TransformError {
    InvalidFactor,
    InvalidMusic(MusicError),
    InvalidTransformOutput {
        transform: &'static str,
        reason: &'static str,
    },
    InvalidStaff(ConversionError),
    Assignment(GraphError),
}

Error returned by transforms that reject invalid scaling factors.

Variants

InvalidFactor

The supplied time-scaling factor was zero or negative.

InvalidMusic(MusicError)

A music object or transform result violated model invariants.

InvalidTransformOutput

A transform returned an output shape that the caller cannot use.

Fields

transform: &'static str

Name of the transform that produced the invalid output.

reason: &'static str

Stable explanation of the invalid condition.

InvalidStaff(ConversionError)

An identity-bearing staff violated its conversion invariants.

Assignment(GraphError)

A certified discrete assignment failed or overflowed.

Trait Implementations

impl Clone for TransformError

fn clone(&self) -> TransformError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransformError

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

Formats the value using the given formatter.

impl Eq for TransformError

impl Error for TransformError

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
