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.

Mysql

An error returned by Mariadb/Mysql

Fields

code: u16

2-byte mysql error code

status: [u8; 5]

5-byte mysql status,

message: String

Error message

Io(Error)

Network error from tokio

Decode(&'static str, DecodeError)

Error decoding row

Bind(u16, BindError)

Error binding parameter

ProtocolError(String)

Mariadb/Mysql did not speak the protocol correctly

ExpectedRows

You executed a mysql statement that does not return any columns

UnexpectedRows

You executed a mysql statement that does return columns, so you need to read the rowss

TooFewListArguments

There where more instances of LIST in the query, than there where list arguments

TooManyListArguments

There where less instances of LIST in the query, than there where list arguments

InvalidUrl

The url supplied is invalid

Trait Implementations

impl Debug for ConnectionErrorContent

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

Formats the value using the given formatter.

impl Display for ConnectionErrorContent

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

Formats the value using the given formatter.

impl Error for ConnectionErrorContent

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<Error> for ConnectionErrorContent

fn from(source: Error) -> Self

Converts to this type from the input type.
