Struct proptest::test_runner::ResultCacheKey

pub struct ResultCacheKey<'a> { /* fields omitted */ }

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.

Methods

impl<'a> ResultCacheKey<'a>

pub fn value_debug(&self) -> &Debug

Return the test input value as an &dyn Debug.

Trait Implementations

impl<'a> Debug for ResultCacheKey<'a>

fn fmt(&self, f: &mut Formatter) -> Result
