Struct Dataset 

#[non_exhaustive]
pub struct Dataset {
    pub identity_id: Option<String>,
    pub dataset_name: Option<String>,
    pub creation_date: Option<DateTime>,
    pub last_modified_date: Option<DateTime>,
    pub last_modified_by: Option<String>,
    pub data_storage: Option<i64>,
    pub num_records: Option<i64>,
}

A collection of data for an identity pool. An identity pool can have multiple datasets. A dataset is per identity and can be general or associated with a particular entity in an application (like a saved game). Datasets are automatically created if they don’t exist. Data is synced by dataset, and a dataset can hold up to 1MB of key-value pairs.

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.

identity_id: Option<String>

A name-spaced GUID (for example, us-east-1:23EC4050-6AEA-7089-A2DD-08002EXAMPLE) created by Amazon Cognito. GUID generation is unique within a region.

dataset_name: Option<String>

A string of up to 128 characters. Allowed characters are a-z, A-Z, 0-9, ‘_’ (underscore), ‘-’ (dash), and ‘.’ (dot).

creation_date: Option<DateTime>

Date on which the dataset was created.

last_modified_date: Option<DateTime>

Date when the dataset was last modified.

last_modified_by: Option<String>

The device that made the last change to this dataset.

data_storage: Option<i64>

Total size in bytes of the records in this dataset.

num_records: Option<i64>

Number of records in this dataset.

Implementations

impl Dataset

pub fn identity_id(&self) -> Option<&str>

A name-spaced GUID (for example, us-east-1:23EC4050-6AEA-7089-A2DD-08002EXAMPLE) created by Amazon Cognito. GUID generation is unique within a region.

pub fn dataset_name(&self) -> Option<&str>

A string of up to 128 characters. Allowed characters are a-z, A-Z, 0-9, ‘_’ (underscore), ‘-’ (dash), and ‘.’ (dot).

pub fn creation_date(&self) -> Option<&DateTime>

Date on which the dataset was created.

pub fn last_modified_date(&self) -> Option<&DateTime>

Date when the dataset was last modified.

pub fn last_modified_by(&self) -> Option<&str>

The device that made the last change to this dataset.

pub fn data_storage(&self) -> Option<i64>

Total size in bytes of the records in this dataset.

pub fn num_records(&self) -> Option<i64>

Number of records in this dataset.

impl Dataset

pub fn builder() -> DatasetBuilder

Creates a new builder-style object to manufacture Dataset.

Trait Implementations

impl Clone for Dataset

fn clone(&self) -> Dataset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dataset

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

Formats the value using the given formatter.

impl PartialEq for Dataset

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