Identifies what went wrong. The human-readable detail is in the Error’s Display output.

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.

Io

An underlying reader or writer failed.

End

The data ended while more bytes were expected.

Str

Bytes that should have been a string were not valid UTF-8.

Tag

A four-character chunk tag, such as MThd, was not the expected one.

VlqTooBig

A variable-length quantity ran past its four-byte maximum.

VlqDecode

A variable-length quantity could not be decoded.

ReadExpect

A byte did not have the one value the spec allows at that position.

FileOpen

A file could not be opened for reading.

FileCreate

A file could not be created for writing.

InvalidFile

The bytes are not a well-formed MIDI file.

RunningStatus

A message relied on running status, but no status byte had been seen yet.

StringTooLong

A string’s length overflows the u32 its length field is stored in.

TooManyTracks

The track count overflows the u16 the header stores it in.

TrackTooLong

A track’s length overflows the u32 its length field is stored in.

Other

Something went wrong that has no more specific classification.

Trait Implementations

impl Ord for ErrorType

fn cmp(&self, other: &ErrorType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for ErrorType

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ErrorType

fn partial_cmp(&self, other: &ErrorType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.
