Module mem 

Memory operations backed by Solana SVM syscalls.

On Solana SBF, these dispatch to sol_memcpy_, sol_memmove_, sol_memcmp_, and sol_memset_. Off-chain, they fall back to standard library implementations.

Functions

bytes_eq

Compare two byte slices for equality using SVM-optimized memcmp.

copy_bytes

Copy bytes from one slice to another (no overlap).

memcmp^⚠

Compare n bytes between two memory regions.

memcpy^⚠

Copy n bytes from src to dst.

memmove^⚠

Copy n bytes from src to dst, handling overlapping regions.

memset^⚠

Fill n bytes starting at dst with byte.

zero_account_data

Zero-fill account data using SVM-optimized memset.

zero_fill

Zero-fill a mutable byte slice using the SVM-optimized memset.
