Struct proptest::test_runner::ResultCacheKey

source · 
pub struct ResultCacheKey<'a> { /* private fields */ }
Expand description

A key used for the result cache.

The capabilities of this structure are currently quite limited; all one can do with safe code is get the &dyn Debug of the test input value. This may improve in the future, particularly at such a time that specialisation becomes stable.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
