Struct ProfilerOptions 

#[non_exhaustive]
pub struct ProfilerOptions {
    pub native_mem: Option<String>,
    /* private fields */
}

Options for configuring the async-profiler behavior. Currently supports:

• Native memory allocation tracking

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

native_mem: Option<String>

If set, the profiler will collect information about native memory allocations.

The value is the interval in bytes or in other units, if followed by k (kilobytes), m (megabytes), or g (gigabytes). For example, "10m" will sample an allocation for every 10 megabytes of memory allocated. Passing "0" will sample all allocations.

See ProfilingModes in the async-profiler docs for more details.

Implementations

impl ProfilerOptions

pub fn to_args_string(&self, jfr_file_path: &Path) -> String

Convert the profiler options to a string of arguments for the async-profiler.

Trait Implementations

impl Debug for ProfilerOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ProfilerOptions

fn default() -> ProfilerOptions

Returns the “default value” for a type.
