pub struct Binary;
Expand description
The binary SQL type.
Schema inference will treat all variants of BLOB
as this type (e.g.
VARBINARY
, MEDIUMBLOB
, etc).

impl FromSql<Binary, Pg> for *const [u8]
The returned pointer is only valid for the lifetime to the argument of
from_sql
. This impl is intended for uses where you want to write a new
impl in terms of Vec<u8>
, but don’t want to allocate. We have to return a
raw pointer instead of a reference with a lifetime due to the structure of
