Variable std.conv.hexString
Converts a hex literal to a string at compile time.
Takes a string made of hexadecimal digits and returns
the matching string by converting each pair of digits to a character.
The input string can also include white characters, which can be used
to keep the literal string readable in the source code.
The function is intended to replace the hexadecimal literal strings
starting with 'x', which could be removed to simplify the core language.
Declaration
void hexString(string hexData) = hexStrImpl(hexData);
Parameters
| Name | Description |
|---|---|
| hexData | string to be converted. |
Returns
a string, a wstring or a dstring, according to the type of hexData.
Example
// conversion at compile time auto string1 = hexString!"304A314B"; assert(string1 == "0J1K"); auto string2 = hexString!"304A314B"w; assert(string2 == "0J1K"w); auto string3 = hexString!"304A314B"d; assert(string3 == "0J1K"d);
