Trait Implementations

impl<'update> AsChangeset for &'update Specimen

type Target = table

The table which Self::Changeset will be updating

type Changeset = <(Grouped<Eq<user_id, <&'update i64 as AsExpression<<user_id as Expression>::SqlType>>::Expression>>, Grouped<Eq<species_id, <&'update i32 as AsExpression<<species_id as Expression>::SqlType>>::Expression>>, Grouped<Eq<created_at, <&'update DateTime<Utc> as AsExpression<<created_at as Expression>::SqlType>>::Expression>>, Grouped<Eq<updated_at, <&'update DateTime<Utc> as AsExpression<<updated_at as Expression>::SqlType>>::Expression>>, Grouped<Eq<size_baby_ratio, <&'update f32 as AsExpression<<size_baby_ratio as Expression>::SqlType>>::Expression>>, Grouped<Eq<size_adult_ratio, <&'update f32 as AsExpression<<size_adult_ratio as Expression>::SqlType>>::Expression>>, Grouped<Eq<lifespan_days_ratio, <&'update f32 as AsExpression<<lifespan_days_ratio as Expression>::SqlType>>::Expression>>, Grouped<Eq<catch_age, <&'update f32 as AsExpression<<catch_age as Expression>::SqlType>>::Expression>>) as AsChangeset>::Changeset

The update statement this type represents

fn as_changeset(self) -> Self::Changeset

Convert self into the actual update statement being executed

The update statement this type represents

fn as_changeset(self) -> Self::Changeset

Convert self into the actual update statement being executed

impl Clone for Specimen

fn clone(&self) -> Specimen

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Specimen

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

Formats the value using the given formatter.

impl Model for Specimen

type Table = table

type PrimaryKeyType = i64

type InsertType = NewSpecimen

fn table() -> Self::Table

fn id(&self) -> Self::PrimaryKeyType

impl PartialEq for Specimen

fn eq(&self, other: &Specimen) -> 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.
