Struct RangeRequestStorage

Source

pub struct RangeRequestStorage { /* private fields */ }

Expand description

Storage backed by a caller-provided byte-range reader.

This is intended for HTTP range requests, S3/object-store clients, or other remote sources that can return exactly the requested byte range.

Implementations§

Source §

impl RangeRequestStorage

Source

pub fn new<F>(len: u64, reader: F) -> RangeRequestStorage
where F: Fn(u64, usize) -> Result<Vec<u8>, Error> + Send + Sync + 'static,

Create a storage backend from a total length and a range reader.
