abseil-string-find-str-contains
|
||
|
|
===============================
|
||
|
|
|
||
|
|
Finds ``s.find(...) == string::npos`` comparisons (for various string-like types)
|
||
|
|
and suggests replacing with ``absl::StrContains()``.
|
||
|
|
|
||
|
|
This improves readability and reduces the likelihood of accidentally mixing
|
||
|
|
``find()`` and ``npos`` from different string-like types.
|
||
|
|
|
||
|
|
By default, "string-like types" includes ``::std::basic_string``,
|
||
|
|
``::std::basic_string_view``, and ``::absl::string_view``. See the
|
||
|
|
StringLikeClasses option to change this.

std::string s = "...";
|
||
|
|
if (s.find("Hello World") == std::string::npos) { /* do something */ }
|
||
|
|
|
||
|
|
absl::string_view a = "...";
|
||
|
|
if (absl::string_view::npos != a.find("Hello World")) { /* do something */ }
|
