The MOZ_MUST_USE
macro is defined as clang's and gcc's nonstandard __attribute__((warn_unused_result))
. Now that we compile as C++17 by default (bug 1560664), we can replace MOZ_MUST_USE
with C++17's standard [[nodiscard]]
attribute.
The [[nodiscard]]
attribute must precede a function declaration's declaration specifiers (like static, extern, inline, or virtual). The __attribute__((warn_unused_result))
attribute does not have this order restriction.
