Struct Enrollment 

pub struct Enrollment {
    pub user_id: String,
    pub course_id: String,
    pub enrolled_at: u64,
    pub progress: f64,
}

A user’s enrollment in a course.

Stored at PK = "USER#<user_id>", SK = "ENROLL#<course_id>". Accessed via Enrollment::get(client, KeyId::pk(user_id).sk(course_id)).

Fields

user_id: String

course_id: String

enrolled_at: u64

progress: f64

Trait Implementations

impl Clone for Enrollment

fn clone(&self) -> Enrollment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Enrollment

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Enrollment

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl DynamoDBItem<PlatformTable> for Enrollment

type AdditionalAttributes = (ItemType, ())

fn to_item(&self) -> Item<TD>

where Self: Serialize,

Serializes self into an Item<TD>.

fn try_from_item(item: Item<TD>) -> Result<Self>

where Self: DeserializeOwned,

Fallibly deserializes an Item<TD> into Self.

fn from_item(item: Item<TD>) -> Self

where Self: DeserializeOwned,

Infallibly deserializes an Item<TD> into Self.

impl HasAttribute<PK> for Enrollment

type Id<'id> = &'id str

The identifier extracted from &self, passed to attribute_value.

type Value = String

A Rust type convertible to the DynamoDB attribute value for this attribute.

fn attribute_id(&self) -> Self::Id<'_>

Extracts the attribute ID from this item.

fn attribute_value(id: Self::Id<'_>) -> Self::Value

Converts an attribute ID into a Rust value of type Self::Value which can then be converted into the correct AttributeValue at serialization using the via IntoTypedAttributeValue.

fn attribute(&self) -> Self::Value

Convenience method: calls attribute_id then attribute_value, returning a Rust value of type Self::Value.

impl HasAttribute<SK> for Enrollment

type Id<'id> = &'id str

The identifier extracted from &self, passed to attribute_value.

type Value = String

A Rust type convertible to the DynamoDB attribute value for this attribute.

fn attribute_id(&self) -> Self::Id<'_>

Extracts the attribute ID from this item.

fn attribute_value(id: Self::Id<'_>) -> Self::Value

Converts an attribute ID into a Rust value of type Self::Value which can then be converted into the correct AttributeValue at serialization using the via IntoTypedAttributeValue.

fn attribute(&self) -> Self::Value

Convenience method: calls attribute_id then attribute_value, returning a Rust value of type Self::Value.

impl HasConstAttribute<ItemType> for Enrollment

const VALUE: Self::Value = "ENROLLMENT"

The constant Rust value shared by all instances of this item type, later converted to the DynamoDB attribute value by the library.

type Value = &'static str

A Rust constant type convertible to the DynamoDB attribute value for this attribute.

impl Serialize for Enrollment

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
