Struct diesel::sql_types::Binary

source · [−]

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<DB: Backend<RawValue = [u8 ]>> FromSql<Binary, DB> 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 FromSql

fn from_sql(bytes: Option<&DB::RawValue>) -> Result<Self>

See the trait documentation.
