Struct BlockCacheTraceOptions 

pub struct BlockCacheTraceOptions { /* private fields */ }

Controls how much of the block cache access stream a block cache trace records.

This is the newer block cache tracing entry point and is paired with BlockCacheTraceWriterOptions. The older entry point reuses TraceOptions instead.

Implementations

impl BlockCacheTraceOptions

pub fn set_sampling_frequency(&mut self, frequency: u64)

Captures one block cache access out of every frequency.

Default: 1, meaning capture every access.

pub fn get_sampling_frequency(&self) -> u64

Returns the current sampling_frequency setting.

See Self::set_sampling_frequency for what this controls.

Trait Implementations

impl Default for BlockCacheTraceOptions

fn default() -> Self

Returns the “default value” for a type.

impl Drop for BlockCacheTraceOptions

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
