Crate expecting

Macros for testing conditions without panicking. The expect_* family of macros cause an early return of an anyhow::Error if the expected condition is not met.

Macros

expect

Expects that the given condition evaluates to true; otherwise returns early.

expect_contains

Expects that the given container (e.g., Vec) contains the element or given string contains the substring; otherwise returns early.

expect_empty

Expects that the given container (e.g., Vec) is empty; otherwise returns early.

expect_eq

Expects that a == b; otherwise returns early.

expect_err

Expects that the given Result is Err and returns the unwrapped error; otherwise returns early.

expect_ne

Expects that a != b; otherwise returns early.

expect_none

Expects that the given Option is None; otherwise returns early.

expect_not_empty

Expects that the given container (e.g., Vec) contains at least one element or given string has non-zero length; otherwise returns early.

expect_ok

Expects that the given Result is Ok and returns its unwrapped contents; otherwise returns early.

expect_some

Expects that the given Option is Some and returns its unwrapped contents; otherwise returns early.

expect_some_eq

Expects that a is Some and its contents are equal to b.
