Trait VortexReadAt

pub trait VortexReadAt: Send + Sync {
    // Required methods
    fn read_at_into(
        &self,
        pos: u64,
        buffer: BytesMut,
    ) -> impl Future<Output = Result<BytesMut>> + Send;
    fn size(&self) -> impl Future<Output = u64>;

    // Provided method
    fn performance_hint(&self) -> usize { ... }
}

Required Methods

fn read_at_into( &self, pos: u64, buffer: BytesMut, ) -> impl Future<Output = Result<BytesMut>> + Send

fn size(&self) -> impl Future<Output = u64>

Size of the underlying file in bytes

Provided Methods

fn performance_hint(&self) -> usize

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.
