Added `std.conv.bitCast`
|
|
||||||
|
|
||||||
This convenience function allows reinterpreting casts to be written in a more
|
|
||||||
readable way.

Extend the functionality of formattedRead to permit a std.file.slurp like execution.
|
|
||||||
|
|
||||||
Template argument types can now be passed to formattedRead along with a
|
|
||||||
format string to parse and read the input range as a Tuple of those arguments.
|
|
||||||
All arguments must be read successfully, otherwise, and unlike std.file.slurp
|
|
||||||
which has non exhaustive option for partial reads, it'll throw a std.format.FormatException.

Added fromHexString and fromHexStringAsRange functions to std.digest.
|
|
||||||
|
|
||||||
This new function enables the converion of a hex string to a range of bytes.
|
|
||||||
Unlike the template $(REF hexString, std, conv) that was designed to supersede
|
|
||||||
a language feature, this function is usable with runtime input.
|
|
||||||
|
|
||||||
The `std.conv` module lacks facilities to conveniently transform the input
|
|
||||||
to a series of bytes directly. Both $(REF parse, std, conv) and $(REF to, std,
|
|
||||||
conv) can only handle the conversion for a single value of the requested target
|
|
||||||
integer type. Furthermore, said functions would allocate a new buffer for the
|
|
||||||
result, while `fromHexStringAsRange` operates lazily by implementing a forward
|
|
||||||
range.
|
|
||||||
|
|
||||||
For further convenience, a validation function $(REF isHexString, std, digest)
|
|
||||||
was added as well.

ODBC Bindings in `etc.c.odbc` have been updated to ODBC 4.0.
|
|
||||||
|
|
||||||
ODBC 4.0, via these new bindings, adds the following functionality:
|
|
||||||
|
|
||||||
1. Support for semi-structured data, such as JSON.
|
|
||||||
2. Collection valued columns.
|
|
||||||
3. Web-based Authorization flows.
|
|
||||||
|
|
||||||
A full list of new features can be found here: https://github.com/Microsoft/ODBC-Specification/blob/master/ODBC%204.0.md
|
|
||||||
|
|
||||||
Additionally these modules add support for 64-bit ODBC interfaces.

Added popGrapheme function to std.uni.
|
|
||||||
|
|
||||||
The new function is a cross between the existing $(REF graphemeStride, std,
|
|
||||||
uni) and $(REF decodeGrapheme, std, uni) functions. The new function both
|
|
||||||
supports `@safe pure nothrow @nogc` like `graphemeStride` does as long as you
|
|
||||||
don't rely on autodecoding (side node: `@nogc` support for `graphemeStride`
|
|
||||||
added in this release), and works with any non-array ranges just like
|
|
||||||
`decodeGrapheme` does.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|

|
|
||||||
// Two Union Jacks of the Great Britain in each

// String pop length in code units, not points.

assert(s.popGrapheme() == 8);

assert(ws.popGrapheme() == 4);

Added `readfln` and `File.readfln` to `std.stdio`
|
|
||||||
|
|
||||||
These functions read a single line of input and parse it using a format string.
|
|
||||||
Unlike `readf`, they will not accidentally read multiple lines if the user
|
|
||||||
forgets to include a line terminator in the format string—a common mistake for
|
|
||||||
beginners.

Added the `SharedAllocatorList`, as the thread-safe version of the regular `AllocatorList`.
|

|
|

The new $(REF SharedAllocatorList, std,experimental,allocator,building_blocks,allocator_list) has the same semantics as the regular `AllocatorList`.
|

Just as the regular `AllocatorList`, if the `BookkeepingAllocator` is `NullAllocator`, the `SharedAllocatorList` will switch to `ouroboros` mode,
|
|

allocationg memory for its own metadata.

New procedural API for `std.sumtype`
|
|
||||||
|
|
||||||
`std.sumtype` has three new convenience functions for querying and retrieving
|
|
||||||
the value of a `SumType` object.
|
|
||||||
|
|
||||||
* `has!T` returns `true` if the `SumType` object has a value of type `T`.
|
|
||||||
* `get!T` returns the value if its type is `T`, or asserts if it is not.
|
|
||||||
* `tryGet!T` returns the value if its type is `T`, or throws an exception if it
|
|
||||||
is not.
|
|
||||||
|
|
||||||
These functions make it easier to write code using `SumType` in a procedural
|
|
||||||
style, as opposed to the functional style encouraged by `match`.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|
||||||
---
|
|
||||||
import std.sumtype;
|
|
||||||
import std.stdio;
|
|
||||||
|
|
||||||
SumType!(string, double) example = "hello";
|
|
||||||
|
|
||||||
if (example.has!string)
|
|
||||||
{
|
|
||||||
writeln("string: ", example.get!string);
|
|
||||||
}
|
|
||||||
else if (example.has!double)
|
|
||||||
{
|
|
||||||
writeln("double: ", example.get!double);
|
|
||||||
}
|
|
||||||
|
|
||||||
try
|
|
||||||
{
|
|
||||||
writeln("double: ", example.tryGet!double);

}
|
|

catch (MatchException e)
|
|
||||||
{
|
|
||||||
writeln("Couldn't get a double.");
