Enum ErrorKind 

pub enum ErrorKind {
    SourceUnavailable,
    PermissionDenied,
    DecodeFailed,
    QuicklookUnavailable,
    ModelUnavailable,
    LibraryBusy,
    LibrarySchema,
    Database,
}

One known failure class. The set is deliberately small: most failures are environmental, and a handful of classes covers them.

Variants

SourceUnavailable

PermissionDenied

DecodeFailed

QuicklookUnavailable

Implementations

impl ErrorKind

pub const ALL: [ErrorKind; 8]

pub fn code(self) -> &'static str

Stable machine code, written to the log. Never rename one: readers and saved logs depend on it.

pub fn remediation(self) -> Option<&'static str>

What the user can do about it, when there is something to do.

pub fn in_chain(err: &Error) -> Option<ErrorKind>

The kind attached anywhere in err’s context chain. Failing that, a SQLite error anywhere in the chain is the database kind: classified by type once, here, rather than tagged at every query.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorKind

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

A short phrase that reads naturally inside {e:#} output.

impl Eq for ErrorKind

impl Error for ErrorKind

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 Hash for ErrorKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ErrorKind

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

Equality operator ==.

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

Inequality operator !=.
