Subject: [PATCH] formatterhelper: fix compilation on 32-bit platforms
|
|
|
|
On 32-bit platforms, size_t and ssize_t are typically typedefs for
|
|
unsigned int and int respectively, which already have built-in
|
|
formatters in std::format and fmt::format.
|
|
|
|
Defining duplicate formatters causes compile-time format string
|
|
checking to fail with errors like:
|
|
error: call to non-'constexpr' function
|
|
'void std::__format::__unmatched_left_brace_in_format_string()'
|
|
|
|
Fix this by only defining the custom size_t/ssize_t formatters on
|
|
64-bit platforms where they are distinct types.
|
|
|
|
