Macro claim::assert_some_eq [−][src]
Asserts that left expression returns Some(T)
variant
and its value of T
type equals to the right expression.
Uses
Assertions are always checked in both debug and release builds, and cannot be disabled.
See debug_assert_some_eq!
for assertions that are not enabled in release builds by default.
Custom messages
This macro has a second form, where a custom panic message can be provided
with or without arguments for formatting. See std::fmt
for syntax for this form.
Examples
let maybe = Some(42); assert_some_eq!(maybe, 42); // With custom messages assert_some_eq!(maybe, 42, "Got some value");
None
variant will cause panic:
ⓘ
let maybe: Option<i32> = None; assert_some_eq!(maybe, 42); // Will panic
