// This file contains simple utilities for performing std::string matching checks.
|
|
// All of these function parameters are specified as `absl::string_view`,
|
|
// meaning that these functions can accept `std::string`, `absl::string_view` or
|
|
// nul-terminated C-style strings.
|
|
//
|
|
// Examples:
|
|
// std::string s = "foo";
|
|
// absl::string_view sv = "f";
|
|
// assert(absl::StrContains(s, sv));
|
|
//
|
|
// Note: The order of parameters in these functions is designed to mimic the
|
|
// order an equivalent member function would exhibit;
|
|
// e.g. `s.Contains(x)` ==> `absl::StrContains(s, x).
