[−][src]Enum multipart::server::ReadEntryResult

pub enum ReadEntryResult<M: ReadEntry, Entry = MultipartField<M>> {
    Entry(Entry),
    End(M),
    Error(M, Error),
}

Ternary result type returned by ReadEntry::next_entry(), Multipart::into_entry() and MultipartField::next_entry().

Variants

Entry(Entry)

The next entry was found.

End(M)

No more entries could be read.

Error(M, Error)

An error occurred.

Methods

impl<M: ReadEntry, Entry> ReadEntryResult<M, Entry>
[src]

pub fn into_result(self) -> Result<Option<Entry>>
[src]

Convert self into Result<Option<Entry>> as follows:

  • Entry(entry) -> Ok(Some(entry))
  • End(_) -> Ok(None)
  • Error(_, err) -> Err(err)

pub fn unwrap(self) -> Entry
[src]

Attempt to unwrap Entry, panicking if this is End or Error.

pub fn expect(self, msg: &str) -> Entry
[src]

Attempt to unwrap Entry, panicking if this is End or Error with the given message. Adds the error's message in the Error case.

pub fn expect_alt(self, end_msg: &str, err_msg: &str) -> Entry
[src]

Attempt to unwrap Entry, panicking if this is End or Error. If this is End, panics with end_msg; if Error, panics with err_msg as well as the error's message.

pub fn unwrap_opt(self) -> Option<Entry>
[src]

Attempt to unwrap as Option<Entry>, panicking in the Error case.

pub fn expect_opt(self, msg: &str) -> Option<Entry>
[src]

Attempt to unwrap as Option<Entry>, panicking in the Error case with the given message as well as the error's message.
