TITLE: Customizing Default Memory Allocator in ckb-std (Rust)
DESCRIPTION: This snippet demonstrates how to customize the `default_alloc!` macro in `ckb-std` to configure the memory heap sizes. It sets the fixed heap size to 4KB, dynamic heap size to 516KB, and minimum dynamic memory block size to 64B. Customizing these values can affect contract verification and runtime behavior, potentially leading to 'out of memory' errors if not tested thoroughly.

LANGUAGE: Rust
CODE:
```
default_alloc!(4 * 1024, 516 * 1024, 64)
```
