Additional Information

contract ID equal to the current contract ID. If a match is found, it returns true, else false.

Returns

• [bool] - true if reentrancy pattern has occured.

Examples

use sway_libs::reentrancy::is_reentrant;

fn foo() {
    assert(is_reentrant() == false);
    // Do critical stuff here
}
