Trait ByteSource 

pub trait ByteSource: Send + Sync {
    // Required methods
    async fn get_size(&self) -> PolarsResult<usize>;
    async fn get_range(&self, range: Range<usize>) -> PolarsResult<Buffer<u8>>;
    async fn get_ranges(
        &self,
        ranges: &mut [Range<usize>],
    ) -> PolarsResult<PlHashMap<usize, Buffer<u8>>>;
}

Available on crate features async or cloud only.

Required Methods

async fn get_size(&self) -> PolarsResult<usize>

async fn get_range(&self, range: Range<usize>) -> PolarsResult<Buffer<u8>>

Panics

Panics if range is not in bounds.

async fn get_ranges( &self, ranges: &mut [Range<usize>], ) -> PolarsResult<PlHashMap<usize, Buffer<u8>>>

Note: This will mutably sort ranges for coalescing.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl ByteSource for DynByteSource

impl ByteSource for BufferByteSource

impl ByteSource for ObjectStoreByteSource
