Struct diesel::sql_types::Binary

pub struct Binary;

The binary SQL type.

Schema inference will treat all variants of BLOB as this type (e.g. VARBINARY, MEDIUMBLOB, etc).

ToSql impls

• Vec<u8>
• &[u8]

FromSql impls

• Vec<u8>

impl Clone for Binary

fn clone(&self) -> Binary

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

Returns the “default value” for a type.

impl FromSql<Binary, Mysql> for *const [u8]

Available on crate feature mysql_backend only.

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(value: MysqlValue<'_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql(bytes: Option<RawValue<'_, DB>>) -> Result<Self>

A specialized variant of from_sql for handling null values.

impl FromSql<Binary, Pg> for *const [u8]

Available on crate feature postgres_backend only.

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(value: PgValue<'_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql(bytes: Option<RawValue<'_, DB>>) -> Result<Self>

A specialized variant of from_sql for handling null values.

impl FromSql<Binary, Sqlite> for *const [u8]

Available on crate feature sqlite only.

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: SqliteValue<'_, '_, '_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql(bytes: Option<RawValue<'_, DB>>) -> Result<Self>

A specialized variant of from_sql for handling null values.

impl HasSqlType<Binary> for Mysql

fn metadata(_: &mut ()) -> MysqlType

Fetch the metadata for the given type

impl HasSqlType<Binary> for Pg

fn metadata(_: &mut Self::MetadataLookup) -> PgTypeMetadata

Fetch the metadata for the given type

impl HasSqlType<Binary> for Sqlite

fn metadata(_: &mut ()) -> SqliteType

Fetch the metadata for the given type

impl QueryId for Binary

type QueryId = Binary

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool = true

Can the SQL generated by Self be uniquely identified by its type?

fn query_id() -> Option<TypeId>

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.

impl SqlType for Binary

type IsNull = NotNull

Is this type nullable?
