# Struct ethcore::trace::NoopTracer [−] [src]

    pub struct NoopTracer;

Nonoperative tracer. Does not trace anything.

## Trait Implementations

### `impl Tracer for NoopTracer`
[src]

#### `fn prepare_trace_call(&self, _: &ActionParams) -> Option<Call>`

Prepares call trace for given params. Noop tracer should return None.

#### `fn prepare_trace_create(&self, _: &ActionParams) -> Option<Create>`

Prepares create trace for given params. Noop tracer should return None.

#### `fn prepare_trace_output(&self) -> Option<Bytes>`

Prepare trace output. Noop tracer should return None.

#### `fn trace_call(&mut self,
call: Option<Call>,
_: U256,
output: Option<Bytes>,
_: Vec<FlatTrace>)`

Stores trace call info.

#### `fn trace_create(&mut self,
create: Option<Create>,
_: U256,
code: Option<Bytes>,
_: Address,
_: Vec<FlatTrace>)`

Stores trace create info.

#### `fn trace_failed_call(&mut self,
call: Option<Call>,
_: Vec<FlatTrace>,
_: TraceError)`

Stores failed call trace.

#### `fn trace_failed_create(&mut self,
create: Option<Create>,
_: Vec<FlatTrace>,
_: TraceError)`

Stores failed create trace.

#### `fn trace_suicide(&mut self,
_address: Address,
_balance: U256,
_refund_address: Address)`

Stores suicide info.

#### `fn subtracer(&self) -> Self`

Spawn subtracer which will be used to trace deeper levels of execution.

#### `fn traces(self) -> Vec<FlatTrace>`

Consumes self and returns all traces.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
