}

Trait to allow a rust type to be translated form a SQL value.

Required methods

fn from_binary(ty: &Type, raw: Option<&[u8]>) -> Result<Self>

Create a new struct from the binary representation.

See the postgresql adt module source code, mainly *_send functions.

fn from_text(ty: &Type, raw: Option<&str>) -> Result<Self>

Create a new struct from the text representation.
