A single character delimiter.

== Synopsis

Declared in `<absl/strings/str_split.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
class ByChar;
----

== Description

`ByChar` is functionally equivalent to a 1‐char string within a `ByString` delimiter, but slightly more efficient.

Example:

// Because a char literal is converted to a absl::ByChar, // the following two splits are equivalent. std::vector<std::string> v1 = absl::StrSplit("a,b,c", ','); using absl::ByChar; std::vector<std::string> v2 = absl::StrSplit("a,b,c", ByChar(',')); // v[0]== "a", v[1]== "b", v[2]== "c"

`ByChar` is also the default delimiter if a single character is given as the delimiter to `StrSplit()`. For example, the following calls are equivalent:

std::vector<std::string> v = absl::StrSplit("a‐b", '‐');

using absl::ByChar; std::vector<std::string> v = absl::StrSplit("a‐b", ByChar('‐'));
