Constant soroban_sdk::xdr::DEFAULT_XDR_RW_DEPTH_LIMIT

pub const DEFAULT_XDR_RW_DEPTH_LIMIT: u32 = 500; // 500u32

Defines the maximum depth for recursive calls in Read/WriteXdr to prevent stack overflow.

The depth limit is akin to limiting stack depth. Its purpose is to prevent the program from hitting the maximum stack size allowed by Rust, which would result in an unrecoverable SIGABRT. For more information about Rust’s stack size limit, refer to the Rust documentation.
