Module symphonia_core::util::bits

Utilities for bit manipulation.

Functions

• contains_ones_byte_u16
  Returns true if the unsigned 16-bit integer contains one or more bytes which have all bits set.
• contains_ones_byte_u32
  Returns true if the unsigned 32-bit integer contains one or more bytes which have all bits set.
• contains_ones_byte_u64
  Returns true if the unsigned 64-bit integer contains one or more bytes which have all bits set.
• mask_at
  Masks the bit at the specified bit index.
• mask_lower
  Masks all bits with an index less than idx.
• mask_lower_eq
  Masks all bits with an index less than or equal to idx.
• mask_range
  Masks out all bits in positions less than upper, but greater than or equal to lower (upper < bit <= lower)
• mask_upper
  Masks all bits with an index greater than idx.
• mask_upper_eq
  Masks all bits with an index greater than or equal to idx.
• sign_extend_leq8_to_i8
  Sign extends an arbitrary, 8-bit or less, signed two’s complement integer stored within an u8 to a full width i8.
• sign_extend_leq16_to_i16
