Trait Implementations

impl<I> Dataset<I, SqliteDatasetError> for SqliteDataset<I>

where I: Clone + Send + Sync + DeserializeOwned,

fn get(&self, index: usize) -> Result<I, SqliteDatasetError>

Get an item from the dataset.

Panics

Panics if index >= len().

fn get_many(&self, indexes: Vec<usize>) -> Result<Vec<I>, SqliteDatasetError>

Get multiple items from the dataset in a single query.

Panics

Panics if indexes[i] >= len().

fn len(&self) -> usize

Return the number of rows in the dataset.

fn is_empty(&self) -> bool

Checks if the dataset is empty.

fn iter(&self) -> DatasetIterator<'_, I, E>

where Self: Sized,

Returns an iterator over the dataset.

impl Dataset<SpeechItem, SqliteDatasetError> for SpeechCommandsDataset

fn get(&self, index: usize) -> Result<SpeechItem, SqliteDatasetError>

Gets the item at the given index.

fn len(&self) -> usize

Gets the number of items in the dataset.

fn get_many(&self, indexes: Vec<usize>) -> Result<Vec<I>, E>

Gets the items at given indexes

fn is_empty(&self) -> bool

Checks if the dataset is empty.

fn iter(&self) -> DatasetIterator<'_, I, E>

where Self: Sized,

Returns an iterator over the dataset.

impl Debug for SqliteDatasetError

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

Formats the value using the given formatter.

impl Display for SqliteDatasetError

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

Formats the value using the given formatter.

impl Error for SqliteDatasetError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
