ReentrancyGuardUpgradeable

Inherits: Initializable

Contract module that helps prevent reentrant calls to a function. Inheriting from ReentrancyGuard will make the nonReentrant modifier available, which can be applied to functions to make sure there are no nested (reentrant) calls to them. Note that because there is a single nonReentrant guard, functions marked as nonReentrant may not call one another. This can be worked around by making those functions private, and then adding external nonReentrant entry points to them. TIP: If EIP-1153 (transient storage) is available on the chain you're deploying at, consider using {ReentrancyGuardTransient} instead. TIP: If you would like to learn more about reentrancy and alternative ways to protect against it, check out our blog post https://blog.openzeppelin.com/reentrancy-after-istanbul/[Reentrancy After Istanbul].

Functions

_getReentrancyGuardStorage

function _getReentrancyGuardStorage() private pure returns (ReentrancyGuardStorage storage $);

__ReentrancyGuard_init

function __ReentrancyGuard_init() internal onlyInitializing;

__ReentrancyGuard_init_unchained

function __ReentrancyGuard_init_unchained() internal onlyInitializing;

nonReentrant

Prevents a contract from calling itself, directly or indirectly. Calling a nonReentrant function from another nonReentrant function is not supported. It is possible to prevent this from happening by making the nonReentrant function external, and making it call a private function that does the actual work.

modifier nonReentrant();

_nonReentrantBefore

function _nonReentrantBefore() private;

_nonReentrantAfter

function _nonReentrantAfter() private;

_reentrancyGuardEntered

Returns true if the reentrancy guard is currently set to "entered", which indicates there is a nonReentrant function in the call stack.

function _reentrancyGuardEntered() internal view returns (bool);

Errors

ReentrancyGuardReentrantCall
