Expand description

Represents all the ways a method can fail within SQLx.

Variants (Non-exhaustive)

This enum is marked as 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.
Configuration(Box<dyn Error + 'static + Sync + Send, Global>)

Error occurred while parsing a connection string.

Database(Box<dyn DatabaseError + 'static, Global>)

Error returned from the database.

Io(Error)

Error communicating with the database backend.

Tls(Box<dyn Error + 'static + Sync + Send, Global>)

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

No rows returned by a query that expected to return at least one row.

TypeNotFound

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

Show fields

Fields of TypeNotFound

type_name: String
ColumnIndexOutOfBounds

Column index was out of bounds.

Show fields

Fields of ColumnIndexOutOfBounds

index: usizelen: usize
ColumnNotFound(String)

No column found for the given name.

ColumnDecode

Error occurred while decoding a value from a specific column.

Show fields

Fields of ColumnDecode

index: Stringsource: Box<dyn Error + 'static + Sync + Send, Global>
Decode(Box<dyn Error + 'static + Sync + Send, Global>)

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

Pool::close was called while we were waiting in Pool::acquire.

WorkerCrashed

A background worker has crashed.
