Enum CromaError 

pub enum CromaError {
    EmptyInput,
    MissingKey,
    NoMusic,
    ParseFailed(Vec<Diagnostic>),
}

Why an ABC conversion failed.

Every failure today is CromaError::ParseFailed, carrying the error diagnostics; an empty file, a missing K: and a tune without music arrive there with the codes abc.file.empty, abc.file.missing_k and abc.file.no_music.

Variants

EmptyInput

👎Deprecated since 1.4.0:

never constructed; an empty source is ParseFailed with code abc.file.empty

MissingKey

👎Deprecated since 1.4.0:

never constructed; a missing K: is ParseFailed with code abc.file.missing_k

NoMusic

👎Deprecated since 1.4.0:

never constructed; a tune without music is ParseFailed with code abc.file.no_music

ParseFailed(Vec<Diagnostic>)

The source has errors; the diagnostics say which and where.
