Implementations

impl Metadata

pub fn from_path<P: AsRef<Path> + ?Sized>( path: &P, orig_path: Option<&P>, ) -> Result<Self, Error>

Collects the metadata for a file. If orig_path is present, it will be used to determine the MIME type instead of path.

This method will return any errors produced by std::fs::metadata(). It will also result in a ErrorKind::InvalidInput error if the path given doesn’t point to a regular file.

pub fn has_failed_precondition(&self, session: &Session) -> bool

Checks If-Match and If-Unmodified-Since headers of the request to determine whether a 412 Precondition Failed response should be produced.

pub fn is_not_modified(&self, session: &Session) -> bool

Checks If-None-Match and If-Modified-Since headers of the request to determine whether a 304 Not Modified response should be produced.

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