Struct RangeHttpBackend 

pub struct RangeHttpBackend { /* private fields */ }

HTTP backend with support for partial/range requests.

This variant supports reading specific byte ranges, which is useful for large files when only a portion is needed.

Implementations

impl RangeHttpBackend

pub fn new(base_url: impl Into<String>) -> Result<Self>

Creates a new range-capable HTTP backend.

Errors

Returns an error if the base URL is invalid.

pub fn get_range(&self, key: &str, start: u64, end: u64) -> Result<Bytes>

Reads a specific byte range from a key.

Arguments

• key - The key to read from
• start - Starting byte offset (inclusive)
• end - Ending byte offset (inclusive)

Errors

Returns an error if the request fails or the server doesn’t support ranges.

pub fn supports_range(&self, key: &str) -> Result<bool>

Checks if the server supports range requests.

Errors

Returns an error if the HTTP HEAD request fails.
