Module std.bitmanip
Bit-level manipulation facilities.
Functions
| Name | Description |
|---|---|
append
|
Takes an integral value, converts it to the given endianness, and appends
it to the given range of ubytes (using put) as a sequence of
T.sizeof ubytes starting at index. hasSlicing!R must be
true.
|
bigEndianToNative
|
Converts the given value from big endian to the native endianness and
returns it. The value is given as a ubyte[n] where n is the size
of the target type. You must give the target type as a template argument,
because there are multiple types with the same size and so the type of the
argument is not enough to determine the return type.
|
bitsSet
|
Range that iterates the indices of the set bits in .
Index 0 corresponds to the least significant bit.
For signed integers, the highest index corresponds to the sign bit.
|
littleEndianToNative
|
Converts the given value from little endian to the native endianness and
returns it. The value is given as a ubyte[n] where n is the size
of the target type. You must give the target type as a template argument,
because there are multiple types with the same size and so the type of the
argument is not enough to determine the return type.
|
nativeToBigEndian
|
Converts the given value from the native endianness to big endian and
returns it as a ubyte[n] where n is the size of the given type.
|
nativeToLittleEndian
|
Converts the given value from the native endianness to little endian and
returns it as a ubyte[n] where n is the size of the given type.
|
peek
|
Takes a range of ubytes and converts the first T.sizeof bytes to
T. The value returned is converted from the given endianness to the
native endianness. The range is not consumed.
|
read
|
Takes a range of ubytes and converts the first T.sizeof bytes to
T. The value returned is converted from the given endianness to the
native endianness. The T.sizeof bytes which are read are consumed from
the range.
|
swapEndian
|
Swaps the endianness of the given integral value or character. |
write
|
Takes an integral value, converts it to the given endianness, and writes it
to the given range of ubytes as a sequence of T.sizeof ubytes
starting at index. hasSlicing!R must be true.
|
Structs
| Name | Description |
|---|---|
BitArray
|
An array of bits. |
DoubleRep
|
Allows manipulating the fraction, exponent, and sign parts of a double separately. The definition is: |
FloatRep
|
Allows manipulating the fraction, exponent, and sign parts of a float separately. The definition is: |
Enum values
| Name | Type | Description |
|---|---|---|
bitfields
|
Allows creating bit fields inside structs and classes. | |
taggedClassRef
|
This string mixin generator allows one to create tagged class reference inside structs and classes. | |
taggedPointer
|
This string mixin generator allows one to create tagged pointers inside structs and classes. |
