Implementations

impl SelfProfiler

pub fn new( output_directory: &Path, crate_name: Option<&str>, event_filters: Option<&[String]>, counter_name: &str ) -> Result<SelfProfiler, Box<dyn Error + Send + Sync>>

pub fn alloc_string<STR: SerializableString + ?Sized>( &self, s: &STR ) -> StringId

Allocates a new string in the profiling data. Does not do any caching or deduplication.

pub fn get_or_alloc_cached_string<A>(&self, s: A) -> StringId

where A: Borrow<str> + Into<String>,

Gets a StringId for the given string. This method makes sure that any strings going through it will only be allocated once in the profiling data.

pub fn map_query_invocation_id_to_string( &self, from: QueryInvocationId, to: StringId )

pub fn bulk_map_query_invocation_id_to_single_string<I>( &self, from: I, to: StringId )

where I: Iterator<Item = QueryInvocationId> + ExactSizeIterator,

pub fn query_key_recording_enabled(&self) -> bool

pub fn event_id_builder(&self) -> EventIdBuilder<'_>
