Implementations

impl DynByteSource

pub fn variant_name(&self) -> &str

Trait Implementations

impl ByteSource for DynByteSource

async fn get_size(&self) -> Result<usize, PolarsError>

async fn get_range(&self, range: Range<usize>) -> Result<MemSlice, PolarsError>

Panics

async fn get_ranges( &self, ranges: &mut [Range<usize>], ) -> Result<HashMap<usize, MemSlice, RandomState>, PolarsError>

Note: This will mutably sort ranges for coalescing.

impl Default for DynByteSource

fn default() -> DynByteSource

Returns the “default value” for a type.

impl From<MemSlice> for DynByteSource

fn from(value: MemSlice) -> DynByteSource

Converts to this type from the input type.

impl From<MemSliceByteSource> for DynByteSource

fn from(value: MemSliceByteSource) -> DynByteSource

Converts to this type from the input type.

impl From<ObjectStoreByteSource> for DynByteSource

fn from(value: ObjectStoreByteSource) -> DynByteSource

Converts to this type from the input type.
