Trait opendal::raw::oio::BlockingRead

pub trait BlockingRead: Send + Sync {
    // Required method
    fn read_at(&self, offset: u64, limit: usize) -> Result<Buffer>;
}

Read is the trait that OpenDAL returns to callers.

Required Methods

fn read_at(&self, offset: u64, limit: usize) -> Result<Buffer>

Read data from the reader at the given offset with the given limit.

Notes

Storage services should try to read as much as possible, only return bytes less than the limit while reaching the end of the file.

Implementations on Foreign Types

impl BlockingRead for ()

fn read_at(&self, offset: u64, limit: usize) -> Result<Buffer>

impl BlockingRead for Bytes

fn read_at(&self, offset: u64, limit: usize) -> Result<Buffer>

impl<T: BlockingRead + ?Sized> BlockingRead for Box<T>

Box<dyn BlockingRead> won’t implement BlockingRead automatically. To make BlockingReader work as expected, we must add this impl.

fn read_at(&self, offset: u64, limit: usize) -> Result<Buffer>
