Trait diesel::deserialize::FromSql

pub trait FromSql<A, DB: Backend>: Sized {
    fn from_sql(bytes: Option<&DB::RawValue>) -> Result<Self>;
}

Deserialize a single field of a given SQL type.

When possible, implementations of this trait should prefer to use an existing implementation, rather than reading from bytes. (For example, if you are implementing this for an enum which is represented as an integer in the database, prefer i32::from_sql(bytes) over reading from bytes directly)

Types which implement this trait should also have #[derive(FromSqlRow)]

Backend specific details

• For PostgreSQL, the bytes will be sent using the binary protocol, not text.
• For SQLite, the actual type of DB::RawValue is private API. All implementations of this trait must be written in terms of an existing primitive.
• For MySQL, the value of bytes will depend on the return value of type_metadata for the given SQL type. See MysqlType for details.
• For third party backends, consult that backend's documentation.

Required Methods
