2018-08-31Add clearer wording to Arc clone example codeOtto Rask-1/+1
2018-08-30Rephrase Arc documentation changes regarding clonesOtto Rask-4/+4
Make it clearer that `Arc::clone()` in fact creates a whole new Arc with the internal pointer pointing to the same location as the source Arc.
2018-08-29Make Arc cloning mechanics clearer in module docsOtto Rask-4/+5
Add some more wording to module documentation regarding how `Arc::clone()` works, as some users have assumed cloning Arc's to work via dereferencing to inner value as follows: use std::sync::Arc; let myarc = Arc::new(1); let myarcref = myarc.clone(); assert!(1 == myarcref); Instead of the actual mechanic of referencing the existing Arc value: use std::sync::Arg; let myarc = Arc::new(1); let myarcref = myarc.clone(); assert!(myarcref == &myarc); // not sure if assert could assert this in the real world

Fixes #44608
2018-07-03Strenghten synchronization in `Arc::is_unique`Ralf Jung-6/+7
Previously, `is_unique` would not synchronize at all with a `drop` that returned early because it was not the last reference, leading to a data race. Fixes #51780
2018-06-29Rename alloc::arc to alloc::sync, to match std::syncSimon Sapin-0/+1936
