Creates a new value of this type from a buffer of data of the specified Postgres Type in its binary format.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be created from the specified Postgres Type.

fn from_sql_null( ty: &Type ) -> Result<Self, Box<dyn Error + Sync + Send, Global>>
