Struct aws_sdk_timestreamwrite::types::Schema

#[non_exhaustive]
pub struct Schema {
    pub composite_partition_key: Option<Vec<PartitionKey>>,
}

A Schema specifies the expected data model of the table.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

composite_partition_key: Option<Vec<PartitionKey>>

A non-empty list of partition keys defining the attributes used to partition the table data. The order of the list determines the partition hierarchy. The name and type of each partition key as well as the partition key order cannot be changed after the table is created. However, the enforcement level of each partition key can be changed.

Implementations

impl Schema

pub fn composite_partition_key(&self) -> &[PartitionKey]

A non-empty list of partition keys defining the attributes used to partition the table data. The order of the list determines the partition hierarchy. The name and type of each partition key as well as the partition key order cannot be changed after the table is created. However, the enforcement level of each partition key can be changed.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .composite_partition_key.is_none().

impl Schema

pub fn builder() -> SchemaBuilder

Creates a new builder-style object to manufacture Schema.

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl PartialEq for Schema

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

This method tests for self and other values to be equal, and is used by ==.

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

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