Enum rbatis_core::error::Error

#[non_exhaustive]pub enum Error {

    Database(Box<dyn DatabaseError>),

}

A generic error that represents all the ways a method can fail inside of rbatis_core.

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.

E(String)

Default Error

Io(Error)

Error communicating with the database.

UrlParse(ParseError)

Connection URL was malformed.

Database(Box<dyn DatabaseError>)

An error was returned by the database.

RowNotFound

No row was returned during query::Map::fetch_one or QueryAs::fetch_one.

ColumnNotFound(Box<str>)

Column was not found by name in a Row (during Row::get).

ColumnIndexOutOfBounds

Column index was out of bounds (e.g., asking for column 4 in a 2-column row).

Fields of ColumnIndexOutOfBounds

index: usizelen: usize

Protocol(Box<str>)

Unexpected or invalid data was encountered. This would indicate that we received data that we were not expecting or it was in a format we did not understand. This generally means either there is a programming error in a rbatis_core driver or something with the connection or the database database itself is corrupted.

Context is provided by the included error message.

PoolTimedOut(Option<Box<dyn StdError + Send + Sync>>)

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.

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

An error occurred while attempting to setup TLS. This should only be returned from an explicit ask for TLS.

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

An error occurred decoding data received from the database.
