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>

Trait Implementations

impl<'expr> AsExpression<Binary> for &'expr Vec<u8>

type Expression = Bound<Binary, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl<'expr2, 'expr> AsExpression<Binary> for &'expr2 &'expr Vec<u8>

type Expression = Bound<Binary, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl AsExpression<Binary> for Vec<u8>

type Expression = Bound<Binary, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl<'expr> AsExpression<Binary> for &'expr [u8]

type Expression = Bound<Binary, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl<'expr2, 'expr> AsExpression<Binary> for &'expr2 &'expr [u8]

type Expression = Bound<Binary, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

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.

impl Debug for Binary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Binary

fn default() -> Binary

Returns the “default value” for a type.

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.

impl QueryId for Binary

type QueryId = Binary

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool

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<DB> ToSql<Binary, DB> for Vec<u8> where
    DB: Backend,
    [u8]: ToSql<Binary, DB>, 

fn to_sql<W: Write>(&self, out: &mut Output<'_, W, DB>) -> Result

See the trait documentation.

impl<DB: Backend> ToSql<Binary, DB> for [u8]

fn to_sql<W: Write>(&self, out: &mut Output<'_, W, DB>) -> Result

See the trait documentation.

impl NotNull for Binary
