Module range 

HTTP Range request parsing and response generation (RFC 7233).

This module provides support for:

• Parsing Range headers (bytes=start-end, bytes=start-, bytes=-suffix)
• Validating ranges against resource sizes
• Generating Content-Range headers
• Building 206 Partial Content responses
• Handling 416 Range Not Satisfiable errors

Example

use fastapi_http::range::{Range, parse_range_header};

let range_header = "bytes=0-499";
let file_size = 1000;

match parse_range_header(range_header, file_size) {
    Ok(ranges) => {
        // Handle partial content response
        for range in ranges {
            println!("Serve bytes {}-{}", range.start, range.end);
        }
    }
    Err(e) => {
        // Return 416 Range Not Satisfiable
    }
}

Structs

ByteRange

A validated byte range within a resource.

Enums

IfRangeResult

Result of validating an If-Range precondition.

RangeError

Errors that can occur when parsing or validating range requests.

RangeSpec

A parsed range specification before validation against resource size.

Functions

accept_ranges_bytes

Generate the Accept-Ranges header value for byte range support.

check_if_range

Check an If-Range precondition header against a validator.

content_range_unsatisfiable

Generate a Content-Range header for an unsatisfiable range.

parse_range_header

Parse a Range header value and resolve it against a resource size.

parse_range_spec

Parse a Range header into a RangeSpec without validating against resource size.

supports_ranges

Check if a request supports range requests based on Accept-Ranges.
