Enum FormatErrorKind 

#[non_exhaustive]
pub enum FormatErrorKind {
    Malformed,
    Invalid,
    Unsupported,
    TooLarge,
    NotFound,
    External,
}

What kind of trouble a FormatError is.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Malformed

The document breaks its format’s syntax: XML that is not well-formed, a token or a number that cannot be read, a file that ends early.

Invalid

The document reads, but says something that cannot be: a value out of range, a reference to nothing, two things that contradict.

Unsupported

Something the reader or the writer does not handle, or that the format has no way to say.

TooLarge

Past a limit the crate sets on what it reads, so that a hostile file cannot exhaust memory or time: elements nested past MAX_DEPTH, more than MAX_MEASURES measures, more than sixteen dots.

NotFound

What was asked for is not in the document: a tune’s reference number, a part.

External

A program the crate runs could not be run, or failed: MuseScore.
