8.222. Tie::SubstrHash

Provides a hash table-like interface to a fixed-sized array that has a constant key size and record size:

require Tie::SubstrHash;
tie %myhash, "Tie::SubstrHash", key_len, value_len, table_size;

To tie a new hash to this package, specify the following:

Length of each key

Length of each value

Size of the table given as the number of key/value pairs

An attempt to store a key/value pair in which either the key or the value is the wrong length, or in which the resulting table would be greater than table_size, results in a fatal error.
