Struct tidb_query_executors::slow_hash_aggr_executor::GroupKeyRefUnsafe

struct GroupKeyRefUnsafe {
    buffer_ptr: NonNull<Vec<u8>>,
    begin: usize,
    end: usize,
}

A reference to a group key slice in the group_key_buffer of SlowHashAggregationImpl.

It is safe as soon as it doesn’t outlive the SlowHashAggregationImpl that creates this reference.

Fields

buffer_ptr: NonNull<Vec<u8>>

Points to the group_key_buffer of SlowHashAggregationImpl

begin: usize

end: usize

impl PartialEq<GroupKeyRefUnsafe> for GroupKeyRefUnsafe

fn eq(&self, other: &GroupKeyRefUnsafe) -> bool

This method tests for self and other values to be equal, and is used by ==.
