Struct Error 

pub struct Error { /* private fields */ }

Represents an error while parsing an SMF file or MIDI stream.

This type wraps an ErrorKind and includes backtrace and error chain data in debug mode. In release mode it is a newtype wrapper around ErrorKind, so the Error::source method always returns None.

If the std feature is enabled, this type implements std::error::Error. Otherwise, only Display and Debug are implemented (the source method on the Error type itself is still available, though).

For more information about the error policy used by midly, see ErrorKind.

Implementations

impl Error

pub fn new(kind: &'static ErrorKind) -> Error

Create a new error with the given ErrorKind.

pub fn kind(&self) -> ErrorKind

More information about the error itself.

pub fn source(&self) -> Option<&Error>

The underlying cause for this error.

Note that this method will always return None in release mode, since error chains are not tracked in release.

This method is available even if the std feature is not enabled.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

Available on crate feature std only.

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<&'static ErrorKind> for Error

fn from(kind: &'static ErrorKind) -> Error

Converts to this type from the input type.
