Bumps once_cell from 0.1.8 to 1.0.1.

Changelog

Sourced from once_cell's changelog.

1.0.1

• fix unsoundness in Lazy<T> if the initializing function panics. Thanks @​xfix!
• implement RefUnwindSafe for Lazy.
• share more code between std and parking_lot implementations.
• add F.A.Q section to the docs.

1.0.0

• remove parking_lot from the list of default features.
• add std default feature. Without std, only unsync module is supported.
• implement Eq for OnceCell.
• fix wrong Sync bound on sync::Lazy.
• run the whole test suite with miri.

0.2.7

• New implementation of sync::OnceCell if parking_lot feature is disabled. It now employs a hand-rolled variant of std::sync::Once.
• sync::OnceCell::get_or_try_init works without parking_lot as well!
• document the effects of parking_lot feature: same performance but smaller types.

0.2.6

• Updated Lazy's Deref impl to requires only FnOnce instead of Fn

0.2.5

• Lazy requires only FnOnce instead of Fn

0.2.4

• nicer fmt::Debug implementation

0.2.3

• update parking_lot to 0.9.0
• fix stacked borrows violation in unsync::OnceCell::get
• implement Clone for sync::OnceCell<T> where T: Clone

0.2.2

• add OnceCell::into_inner which consumes a cell and returns an option

0.2.1

• implement sync::OnceCell::get_or_try_init if parking_lot feature is enabled
• switch internal unsafe implementation of sync::OnceCell from Once to Mutex
• sync::OnceCell::get_or_init is twice as fast if cell is already initialized
• implement std::panic::RefUnwindSafe and std::panic::UnwindSafe for OnceCell
