Module r3_kernel::utils

Utility

This module is exempt from the API stability guarantee unless specified otherwise. It’s exposed mostly because it’s needed by macros.

Modules

• binary_heap
  Binary heap with a contextful comparator and position tracking
• mem

Structs

• AlignedStorage
  Untyped storage of the specified size and alignment. This is analogous to C++’s std::aligned_storage_t.
• Frozen
  Erases interior mutability by preventing reference forming.
• RawCell
  Like UnsafeCell, but implements Sync.

Constants

• FIXED_PRIO_BITMAP_MAX_LEN
  The maximum bit count supported by FixedPrioBitmap.

Traits

• BinInteger
  Integral types with efficient binary operations.
• BinUInteger
  Unsigned integral types with efficient binary operations.
• Init
  Trait for types having a constant default value. This is essentially a constant version of Default.
• PrioBitmap
  Trait for FixedPrioBitmap.
• Zeroable
  Trait for types that can be safely created with zeroed.

Type Definitions

• FixedPrioBitmap
  A bit array structure supporting logarithmic-time bit scan operations.
• UIntegerWithBound
  Get the smallest unsigned integer type capable of representing the specified value.

Derive Macros

• Zeroable
  Derive the Zeroable trait for a struct
