Implementations

impl SelfProfiler

pub fn new(
    output_directory: &Path,
    crate_name: Option<&str>,
    event_filters: &Option<Vec<String>>
) -> 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<'_>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
