Trait Implementations

impl Clone for EntityHistoryChangeReason

fn clone(&self) -> EntityHistoryChangeReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityHistoryChangeReason

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

Formats the value using the given formatter.

impl<'r> Decode<'r, Postgres> for EntityHistoryChangeReason

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

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

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

where &'q str: Encode<'q, DB>,

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

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 EntityHistoryChangeReason

fn eq(&self, other: &EntityHistoryChangeReason) -> 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 PgHasArrayType for EntityHistoryChangeReason

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl Type<Postgres> for EntityHistoryChangeReason

fn type_info() -> PgTypeInfo

Returns the canonical SQL type for this Rust type.

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

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