Implementations

impl SingleBlockPresence

pub fn is_missing(self) -> bool

Trait Implementations

impl Clone for SingleBlockPresence

fn clone(&self) -> SingleBlockPresence

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SingleBlockPresence

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

Formats the value using the given formatter.

impl<'r, DB: Database> Decode<'r, DB> for SingleBlockPresence

where u8: Decode<'r, DB>,

fn decode( value: <DB as Database>::ValueRef<'r>, ) -> Result<Self, Box<dyn Error + Send + Sync + 'static>>

Decode a new value of this type using a raw value from the database.

impl<'de> Deserialize<'de> for SingleBlockPresence

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'q, DB: Database> Encode<'q, DB> for SingleBlockPresence

where u8: Encode<'q, DB>,

fn encode_by_ref( &self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn size_hint(&self) -> usize

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

impl PartialEq for SingleBlockPresence

fn eq(&self, other: &SingleBlockPresence) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SingleBlockPresence

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<DB: Database> Type<DB> for SingleBlockPresence

where u8: Type<DB>,

fn type_info() -> DB::TypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &DB::TypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.
