Variants

Configuration(Box<dyn Error + Sync + Send>)

Error occurred while parsing a connection string.

Database(Box<dyn DatabaseError>)

Error returned from the database.

Io(Error)

Tls(Box<dyn Error + Sync + Send>)

Error occurred while attempting to establish a TLS connection.

Protocol(String)

Unexpected or invalid data encountered while communicating with the database.

This should indicate there is a programming error in a SQLx driver or there is something corrupted with the connection to the database itself.

RowNotFound

TypeNotFound

Type in query doesn’t exist. Likely due to typo or missing user type.

Fields

type_name: String

ColumnIndexOutOfBounds

Column index was out of bounds.

Fields

index: usize

len: usize

ColumnNotFound(String)

No column found for the given name.

ColumnDecode

Error occurred while decoding a value from a specific column.

Fields

index: String

source: Box<dyn Error + Sync + Send>

Decode(Box<dyn Error + Sync + Send>)

Error occurred while decoding a value.

PoolTimedOut

A Pool::acquire timed out due to connections not becoming available or because another task encountered too many errors while trying to open a new connection.

PoolClosed
