impl Clone for CourseRole

fn clone(&self) -> CourseRole

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CourseRole

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

Formats the value using the given formatter.

impl Default for CourseRole

fn default() -> CourseRole

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CourseRole

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromSql<Text, Pg> for CourseRole

fn from_sql(bytes: Option<&<Pg as Backend>::RawValue>) -> Result<Self>

See the trait documentation.

impl<__ST, __DB> FromSqlRow<__ST, __DB> for CourseRole

where __DB: Backend, Self: FromSql<__ST, __DB>,

fn build_from_row<R: Row<__DB>>(row: &mut R) -> Result<Self>

See the trait documentation.

const FIELDS_NEEDED: usize = 1usize

The number of fields that this type will consume. Must be equal to the number of times you would call row.take() in build_from_row

impl PartialEq for CourseRole

fn eq(&self, other: &CourseRole) -> 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<__ST, __DB> Queryable<__ST, __DB> for CourseRole

where __DB: Backend, Self: FromSql<__ST, __DB>,

type Row = CourseRole

The Rust type you’d like to map from.

fn build(row: Self::Row) -> Self

Construct an instance of this type

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<__DB> ToSql<Nullable<Text>, __DB> for CourseRole

where __DB: Backend, Self: ToSql<Varchar, __DB>,

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

See the trait documentation.

impl ToSql<Text, Pg> for CourseRole

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

See the trait documentation.
