This Rust crate provides the macro assure! and its friends. These are similar to the macro assert! and its friends.
assure!(condition) will return Result with Ok(true) or Err(message).
assert!(condition) will return successfully or will call panic!.
Macro for truth checking:
assure!(a): assure a is true.Macros for value comparison:
assure_eq!(a, b): assure a is equal to b.
assure_ne!(a, b): assure a is not equal to b.
assure_lt!(a, b): assure a is less than b.
assure_le!(a, b): assure a is less than or equal to b.
assure_gt!(a, b): assure a is greater than b.
assure_ge!(a, b): assure a is greater than or equal to b.
Macros for iterator sets, such as arrays and vectors:
assure_set_eq(a, b): assure the set a is equal to the set b.
assure_set_ne(a, b): assure the set a is not equal to the set b.
Macro for IO-related truth checking, which returns Err(std::io::Error(…)):
assure_io!(a): assure a is true.Macros for IO-related value comparison, which returns Err(std::io::Error(…)):
assure_io_eq!(a, b): assure a is equal to b.
