Struct wasmedge_sdk::Statistics
source · pub struct Statistics { /* private fields */ }
Expand description
Used to collect statistics of the WasmEdge runtime, such as the count of instructions in execution.
Implementations§
source§impl Statistics
impl Statistics
sourcepub fn new() -> WasmEdgeResult<Self>
pub fn new() -> WasmEdgeResult<Self>
sourcepub fn count_per_second(&self) -> f64
pub fn count_per_second(&self) -> f64
Returns the instruction count per second in execution.
Notice
For the following cases,
- Statistics is not enabled, or
- the total execution time is 0
The instructions per second could be NaN
, which represents divided-by-zero
.
Use the is_nan
function of F64 to check the return value before use it,
for example,
use wasmedge_sdk::Statistics;
// create a Statistics instance
let stat = Statistics::new().expect("fail to create a Statistics");
// check instruction count per second
assert!(stat.count_per_second().is_nan());

pub fn set_cost_table(&mut self, cost_table: impl AsRef<[u64]>)
