Enum ConnectorError 

pub enum ConnectorError {
    Database(SqlxErrorKind, String),
    Connection(SqlxErrorKind, String),
    RowDecode(SqlxErrorKind, String),
    Core(Error),
}

Error type for database connector operations.

This covers everything that can go wrong at runtime when talking to a database. Query-building errors are represented by nautilus_core::Error and can be wrapped via the ConnectorError::Core variant.

Each variant that originates from a sqlx error carries a SqlxErrorKind discriminant for programmatic inspection (e.g. constraint violations vs I/O errors) without storing the non-Clone sqlx::Error itself.

Variants

Database(SqlxErrorKind, String)

A query was executed successfully but the database returned an error.

Connection(SqlxErrorKind, String)

Could not establish or acquire a database connection.

RowDecode(SqlxErrorKind, String)

A row could not be decoded into the expected Rust types.

Core(Error)

A query-building error originating from nautilus-core.

Implementations

impl ConnectorError

pub fn database(e: Error, context: &str) -> Self

Create a Database error from a sqlx error with a context message.

pub fn connection(e: Error, context: &str) -> Self

Create a Connection error from a sqlx error with a context message.

pub fn row_decode(e: Error, context: &str) -> Self

Create a RowDecode error from a sqlx error with a context message.

pub fn database_msg(msg: impl Into<String>) -> Self

Create a Database error from a plain message (no sqlx source).

pub fn connection_msg(msg: impl Into<String>) -> Self

Create a Connection error from a plain message (no sqlx source).

pub fn row_decode_msg(msg: impl Into<String>) -> Self

Create a RowDecode error from a plain message (no sqlx source).

pub fn sqlx_kind(&self) -> SqlxErrorKind

Returns the SqlxErrorKind for this error, if applicable.

Trait Implementations

impl Clone for ConnectorError

fn clone(&self) -> ConnectorError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectorError

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

Formats the value using the given formatter.

impl Display for ConnectorError

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

Formats the value using the given formatter.

impl Error for ConnectorError

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 ConnectorError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl PartialEq for ConnectorError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
