Struct ImapMessageSort 

pub struct ImapMessageSort { /* private fields */ }

I/O-free IMAP SORT coroutine with a SEARCH + FETCH client-side fallback.

With fallback == false it sends a plain server SORT. With fallback == true it SEARCHes the candidates, FETCHes the sort keys, and sorts locally, returning the same Vec<NonZeroU32> either way.

Implementations

impl ImapMessageSort

pub fn new( sort_criteria: Vec1<SortCriterion>, search_criteria: Vec1<SearchKey<'static>>, opts: ImapMessageSortOptions, ) -> Self

Creates a coroutine that sorts the messages matching search_criteria by sort_criteria, server-side or locally.

opts.fallback selects the SEARCH + FETCH client-side path and opts.uid the UID variant of every command involved.

Trait Implementations

impl ImapCoroutine for ImapMessageSort

type Yield = ImapYield

The request type yielded while the coroutine progresses.

type Return = Result<Vec<NonZero<u32>>, ImapMessageSortError>

The final value produced on completion.

fn resume( &mut self, fragmentizer: &mut Fragmentizer, arg: Option<&[u8]>, ) -> ImapCoroutineState<Self::Yield, Self::Return>

Pass None initially or after a WantsWrite, Some(bytes) after a WantsRead, Some(&[]) on EOF.
