Why is data location not required to be specified for bytes32?

  • Hello. Please give us more details about your question. What do you mean by "data location not required" ? What exactly are you talking about ? What type would require it ? May 3 at 9:07

    @FlorianCastelain In solidity, there are 4 types of data location: storage, calldata, stack and memory. Data location must be explicitly specified in solidity for arrays, bytes and structs. May 3 at 20:06

Whether or not you need to declare memory, storage, or calldata depends on if your variable is a "complex" variable or not. (See the note here.) This means things like structs and arrays. Simpler types are automatically assigned storage - see this question and anwser.

To answer fully, bytes32 will automatically be storage even without a data location declaration.

    Thanks, that fully answered it! May 3 at 20:07
  • bytes is a monster that probably should have gotten a different name to distinguish it further from the simple types like bytes32.
