Struct zarrs::array::codec::ArrayPartialDecoderCache

pub struct ArrayPartialDecoderCache<'a> { /* private fields */ }

A cache for an ArrayPartialDecoderTraits partial decoder.

Implementations

impl<'a> ArrayPartialDecoderCache<'a>

pub fn new( input_handle: &dyn ArrayPartialDecoderTraits, decoded_representation: ChunkRepresentation, options: &CodecOptions ) -> Result<Self, CodecError>

Create a new partial decoder cache.

Errors

Returns a CodecError if initialisation of the partial decoder fails.

pub async fn async_new( input_handle: &dyn AsyncArrayPartialDecoderTraits, decoded_representation: ChunkRepresentation, options: &CodecOptions ) -> Result<ArrayPartialDecoderCache<'a>, CodecError>

Available on crate feature async only.

Create a new asynchronous partial decoder cache.

Errors

Returns a CodecError if initialisation of the partial decoder fails.
