Synopsis¶

size_type bucket( const Key& key ) const; (since C++11)

to key are always found in this bucket. The returned value is valid only for
instances of the container for which bucket_count() returns the same value.

The behavior is undefined if bucket_count() is zero.

Parameters¶

key - the value of the key to examine

Return value¶

Bucket index for the key key.
