//! # How the Merge Algorithm works
//!
//! Each extractor create #Threads caches and balances the entries
//! based on the hash of the keys. To do that we can use the
//! hashbrown::hash_map::RawEntryBuilderMut::from_key_hashed_nocheck.
//! This way we can compute the hash on our own, decide on the cache to
//! target, and insert it into the right HashMap.
//!
//! #Thread -> caches
//! t1 -> [t1c1, t1c2, t1c3]
//! t2 -> [t2c1, t2c2, t2c3]
//! t3 -> [t3c1, t3c2, t3c3]
//!
//! When the extractors are done filling the caches, we want to merge
//! the content of all the caches. We do a transpose and each thread is
//! assigned the associated cache. By doing that we know that every key
//! is put in a known cache and will collide with keys in the other
//! caches of the other threads.
//!
//! #Thread -> caches
//! t1 -> [t1c1, t2c1, t3c1]
//! t2 -> [t1c2, t2c2, t3c2]
//! t3 -> [t1c3, t2c3, t3c3]
//!
//! When we encountered a miss in the other caches we must still try
//! to find it in the spilled entries. This is the reason why we use
//! a grenad sorter/reader so that we can seek "efficiently" for a key.
//!
//! ## More Detailled Algorithm
//!
//! Each sub-cache has an in-memory HashMap and some spilled
//! lexicographically ordered entries on disk (grenad). We first iterate
//! over the spilled entries of all the caches at once by using a merge
//! join algorithm. This algorithm will merge the entries by using its
//! merge function.
//!
//! Everytime a merged entry is emited by the merge join algorithm we also
//! fetch the value from the other in-memory caches (HashMaps) to finish
//! the merge. Everytime we retrieve an entry from the in-memory caches
//! we mark them with a tombstone for later.
//!
//! Once we are done with the spilled entries we iterate over the in-memory
//! HashMaps. We iterate over the first one, retrieve the content from the
//! other onces and mark them with a tombstone again. We also make sure
//! to ignore the dead (tombstoned) ones.
//!
//! ## Memory Control
//!
//! We can detect that there are no more memory available when the
//! bump allocator reaches a threshold. When this is the case we
//! freeze the cache. There is one bump allocator by thread and the
//! memory must be well balanced as we manage one type of extraction
//! at a time with well-balanced documents.
//!
//! It means that the unknown new keys added to the
//! cache are directly spilled to disk: basically a key followed by a
//! del/add bitmap. For the known keys we can keep modifying them in
//! the materialized version in the cache: update the del/add bitmaps.
//!
//! For now we can use a grenad sorter for spilling even thought I think
//! it's not the most efficient way (too many files open, sorting entries).

/// A trait for types that are **not** [`Send`] only because they would then allow concurrent access to a type that is not [`Sync`].
///
/// The primary example of such a type is `&T`, with `T: !Sync`.
///
/// In the authors' understanding, a type can be `!Send` for two distinct reasons:
///
/// 1. Because it contains data that *genuinely* cannot be moved between threads, such as thread-local data.
/// 2. Because sending the type would allow concurrent access to a `!Sync` type, which is undefined behavior.
///
/// `MostlySend` exists to be used in bounds where you need a type whose data is **not** *attached* to a thread
/// because you might access it from a different thread, but where you will never access the type **concurrently** from
/// multiple threads.
///
/// Like [`Send`], `MostlySend` assumes properties on types that cannot be verified by the compiler, which is why implementing
/// this trait is unsafe.
///
/// # Safety
///
/// Implementers of this trait promises that the following properties hold on the implementing type:
///
/// 1. Its data can be accessed from any thread and will be the same regardless of the thread accessing it.
/// 2. Any operation that can be performed on the type does not depend on the thread that executes it.
///
/// As these properties are subtle and are not generally tracked by the Rust type system, great care should be taken before
/// implementing `MostlySend` on a type, especially a foreign type.
///
/// - An example of a type that verifies (1) and (2) is [`std::rc::Rc`] (when `T` is `Send` and `Sync`).
/// - An example of a type that doesn't verify (1) is thread-local data.
/// - An example of a type that doesn't verify (2) is [`std::sync::MutexGuard`]: a lot of mutex implementations require that
/// a lock is returned to the operating system on the same thread that initially locked the mutex, failing to uphold this
/// invariant will cause Undefined Behavior
/// (see last § in [the nomicon](https://doc.rust-lang.org/nomicon/send-and-sync.html)).
///
/// It is **always safe** to implement this trait on a type that is `Send`, but no placeholder impl is provided due to limitations in
/// coherency. Use the [`FullySend`] wrapper in this situation.
