Struct HttpFile 

pub struct HttpFile { /* private fields */ }

An remote file accessed over HTTP. Implements AsyncRead and AsyncSeek traits.

• Supports seeking and reading at arbitrary positions.
• Uses HTTP Range requests to fetch data.
• Handles transient network errors with retries.
• stream_position() is cheap, as it is tracked locally.

Implementations

impl HttpFile

pub fn url(&self) -> &Url

url of the file

pub fn content_length(&self) -> Option<u64>

content length of the file(in bytes), if present

pub fn etag(&self) -> Option<&str>

etag of the file, if present

pub fn mime(&self) -> Option<&str>

Mime type of the file, if present

impl HttpFile

pub async fn new(client: Client, url: &str) -> Result<Self>

Create a new HttpFile from a reqwest::Client and a file URL.

Arguments:

• client: A reqwest::Client instance to make HTTP requests.
• url: The URL of the file to access.

Trait Implementations

impl AsyncRead for HttpFile

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut ReadBuf<'_>, ) -> Poll<Result<()>>

Attempts to read from the AsyncRead into buf.

impl AsyncSeek for HttpFile

fn start_seek(self: Pin<&mut Self>, position: SeekFrom) -> Result<()>

Attempts to seek to an offset, in bytes, in a stream.

fn poll_complete( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<u64>>

Waits for a seek operation to complete.

impl Debug for HttpFile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
