topo
The topo crate provides incremental caching and identifiers for repeated function invocations. Together with a change notification mechanism it can be used to implement a form of incremental computing.
[0.11.0] - 2020-07-06
Added
cache::Hashed
holds a query key and its hash for later storage.
Changed
cache::{Cache, LocalCache}::get_if_arg_eq_input
now returnsErr(Hashed)
rather thanNone
when a lookup fails. Thestore
function on both types now requires thatHashed
to be passed when inserting new input & output.- Cache contents are GC'd in a single loop, previously there were two iterations over each namespace.
Fixed
- This release removes the last "known redundant" work in the cache API.
[0.10.0] - 2020-07-05
Fixed
Id
generation is no longer vulnerable to hashing collisions.
Added
- #[nested] allows specifying a
slot
. cache::{Cache, GlobalCache}
types for storing interned and memoized values.cache::{SharedCache, SharedGlobalCache}
types for safe multiple-owner access to caches, implementingcache_with
with careful locking to allow nested calls in the future.root
free function for allowing one to re-root a call topology (i.e. if running inside of a broader one).
Removed
Callsite
andPoint
are no longerpub
.#![feature(track_caller)]
is no longer needed, although until 1.46 hits beta/stable an MSRV of nightly-2020-07-02 applies.
Changed
call_in_slot
accepts borrowed slots.Id
renamed toCallId
.illicit
dependency updated to 1.0.impl Trait
has been removed from public APIs where it may cause accidentalSend
/!Send
contracts.
[0.9.4] - 2019-12-26
Changed
- Updated
illicit
dependency to0.9.0
.
[0.9.3] - 2019-12-25
Changed
#[track_caller]
is used to generateId
s, replacing macros. Requires nightly for now.- Use
DefaultHasher
instead ofFnvHasher
.
Added
call
,call_in_slot
functions.
Removed
call!
andunstable_make_topo_macro!
macros.
[0.9.2] - 2019-11-23
Changed
- Using
fnv
crate for hashingId
s.
[0.9.1] - 2019-11-21
Removed
#![warn(intra_doc_resolution_failure)]
was causing docs.rs issues due to root_html_url.
[0.9.0] - 2019-11-19
Added
#![forbid(unsafe_code)]
call!
accepts a "slot" other than the number of times a callsite has been seen. The callsite count is still the default.- Invoking
call!
when noPoint
has already been entered will now create a new root and enter it before executing the block.
Changed
- Rename
#[bound]
to#[nested]
. - Rename
current_callsite_count
toCallsite::current_count
.
Removed
env!
,Env
,#[from_env]
moved toillicit
crate.root!
removed in favor of creating a new root whenevercall!
is invoked outside of aPoint
.
[0.8.2] - 2019-08-20
Fixed
root!
no longer hides the outer environment from the called block.
[0.8.1] - 2019-08-17
Changed
Id
'sDebug
impl uses hex.
Fixed
- Incorrect line endings.
[0.8.0] - 2019-06-23
Added
#[topo::bound]
attaches a function to the topology.root!
andcall!
macros attach arbitrary blocks to a new or the current topology respectively, entering newPoint
s for each call, each of which has a (mostly) uniqueId
.env!
macro allows declaring type-indexed implicit variables, producesEnv
instances.
[0.1.0] - 2019-05-26
