}Expand description
Given a TestRunner and a strategy, it generates calls. Used inside the Fuzzer inspector to override external calls to test for potential reentrancy vulnerabilities..
Fields§
§test_address: AddressAddress of the test contract.
runner: Arc<Mutex<TestRunner>>Runner that will generate the call from the strategy.
strategy: SBoxedStrategy<Option<CallDetails>>Strategy to be used to generate calls from target_reference.
target_reference: Arc<RwLock<Address>>Reference to which contract we want a fuzzed calldata from.
used: boolFlag to know if a call has been overridden. Don’t allow nesting for now.
replay: boolIf set to true, consumes the next call from last_sequence, otherwise queries it from
the strategy.
last_sequence: Arc<RwLock<Vec<Option<BasicTxDetails>>>>Saves the sequence of generated calls that can be replayed later on.
Implementations§
Source§impl RandomCallGenerator
impl RandomCallGenerator
pub fn new( test_address: Address, runner: TestRunner, strategy: impl Strategy<Value = CallDetails> + Send + Sync + 'static, target_reference: Arc<RwLock<Address>>, ) -> Self
Sourcepub fn set_replay(&mut self, status: bool)
pub fn set_replay(&mut self, status: bool)
All self.next() calls will now pop self.last_sequence. Used to replay an invariant
failure.
Sourcepub fn next(
&mut self,
original_caller: Address,
original_target: Address,
) -> Option<BasicTxDetails>
pub fn next( &mut self, original_caller: Address, original_target: Address, ) -> Option<BasicTxDetails>
Gets the next call. Random if replay is not set. Otherwise, it pops from last_sequence.

§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();§fn bright_black(&self) -> Painted<&T>

§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().
use yansi::Paint;
painted.on_red();§fn on_primary(&self) -> Painted<&T>

§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling [Attribute] value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi [Quirk] value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition] value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);§impl<T> Pipe for Twhere
