PartialEq
).

Concatenates literals into a static string slice.
Asserts that a boolean expression is true
at runtime.
Asserts that two expressions are equal to each other.
Asserts that two expressions are not equal to each other.
Inspects an environment variable at compile time.
Expands to the file name in which it was invoked.
Constructs parameters for the other string-formatting macros.
Parses a file as an expression or an item according to the context.
