Security
This crate provides components to handle common security-related tasks.
Initializable
use openzeppelin_security::InitializableComponent;Component enabling one-time initialization for contracts.
Embeddable Implementations

Internal Implementations
InternalImpl
Embeddable functions
is_initialized(self: @ComponentState) → bool
external
#Returns whether the contract has been initialized.
Internal functions
initialize(ref self: ComponentState)
internal
#Initializes the contract. Can only be called once.
Requirements:
- the contract must not have been initialized before.
Pausable
use openzeppelin_security::PausableComponent;Component to implement an emergency stop mechanism.

Events
Embeddable functions
is_paused(self: @ComponentState) → bool
external
#Returns whether the contract is currently paused.
Internal functions
assert_not_paused(self: @ComponentState)
internal
#Panics if the contract is paused.
assert_paused(self: @ComponentState)
internal
#Panics if the contract is not paused.
Events
Paused(account: ContractAddress)
event
#Emitted when the contract is paused by account.
Unpaused(account: ContractAddress)
event
#Emitted when the contract is unpaused by account.
ReentrancyGuard
use openzeppelin_security::ReentrancyGuardComponent;Component to help prevent reentrant calls.
Internal Implementations
InternalImpl
Internal functions
start(ref self: ComponentState)
internal
#Prevents a contract's function from calling itself or another protected function, directly or indirectly.
Requirements:
- the guard must not be currently enabled.
end(ref self: ComponentState)
internal
#Removes the reentrant guard.
