Struct Range 

pub struct Range {
    pub start: u64,
    pub end: u64,
}

Fields

start: u64

end: u64

The most ranges served as parts; more become one range of the whole file (RFC 9110 §14.2 lets a server coalesce or ignore ranges).

pub fn parse_range_in_content_range( filelength: u64, range_str: &str, ) -> Result<Range, Error>

Parse one first-last / first- / -suffix byte range against a resource of filelength bytes (RFC 9110 §14.1.2). The returned end is inclusive (bytes=0-0 is one byte). A last past the end is clamped to the last byte and a suffix longer than the resource selects all of it; a range starting at or past the end, first > last, or any range on an empty resource is 416 Range Not Satisfiable.

pub fn parse_content_range( filepath: &str, filelength: u64, raw_range_value: &str, ) -> Result<Vec<ContentRange>, Error>

pub fn coalesce(ranges: Vec<Range>, filelength: u64) -> Vec<Range>

ranges (inclusive ends) as served: kept as requested when none overlap; otherwise sorted with the overlapping ones merged — so a response never holds more bytes than the file has; and more than MAX_RANGES parts become the whole file.

pub fn get_content_range_list( request_uri: &str, range: &Header, ) -> Result<Vec<ContentRange>, Error>

pub fn _parse_multipart_body( cursor: &mut Cursor<&[u8]>, content_range_list: Vec<ContentRange>, ) -> Result<Vec<ContentRange>, String>

pub fn _parse_raw_content_range_header_value( unparsed_header_value: &str, ) -> Result<(i64, i64, i64), String>

pub fn _parse_content_range_header_value( header_value: String, ) -> Result<(i64, i64, i64), String>

pub fn _parse_line_as_bytes(cursor: &mut Cursor<&[u8]>) -> Vec<u8>

pub fn _convert_bytes_array_to_string(buffer: Vec<u8>) -> String

pub fn get_content_range(body: Vec<u8>, mime_type: String) -> ContentRange

Creates a ContentRange from raw bytes and a MIME type. The most common way to build a response body.

pub fn get_content_range_of_a_file( filepath: &str, ) -> Result<ContentRange, String>

Creates a ContentRange by reading a file from disk. MIME type is detected from the extension.

pub fn parse_multipart_body( cursor: &mut Cursor<&[u8]>, content_range_list: Vec<ContentRange>, ) -> Result<Vec<ContentRange>, String>

pub fn parse_multipart_body_with_boundary( cursor: &mut Cursor<&[u8]>, content_range_list: Vec<ContentRange>, boundary: String, total_bytes: i32, bytes_read: i32, is_opening_boundary_read: bool, ) -> Result<Vec<ContentRange>, String>

pub fn parse_line_as_bytes( cursor: &mut Cursor<&[u8]>, ) -> Result<Vec<u8>, String>

pub fn convert_bytes_array_to_string(buffer: Vec<u8>) -> Result<String, String>
