pub enum Error {
    Sql(Error),
    Migration(MigrateError),
    InvalidDbUrl(String),
    DatabaseNotLoaded(String),
    UnsupportedDatatype(String),
}

Errors that can happen while connecting to a database, running migrations or executing a query.

Variants

Sql(Error)

An error reported by sqlx, such as a failed connection or a query the database rejected.

Migration(MigrateError)

A migration registered with crate::Builder::add_migrations could not be resolved or applied.

InvalidDbUrl(String)

The connection string is missing its scheme: prefix, or the scheme does not match any of the enabled database drivers. Contains the offending connection string.

DatabaseNotLoaded(String)

The requested database has not been connected to with the load command and is not listed in the plugin’s preload configuration. Contains the connection string of the database.

UnsupportedDatatype(String)

A value selected from the database has a SQL type that cannot be converted to JSON. Contains the name of that SQL type.
