Struct dashmap::SharedValue

#[repr(transparent)]
pub struct SharedValue<T> { /* private fields */ }

A simple wrapper around T

This is to prevent UB when using HashMap::get_key_value, because HashMap doesn’t expose an api to get the key and value, where the value is a &mut T.

See #10 for details

This type is meant to be an implementation detail, but must be exposed due to the Dashmap::shards
