Struct SortKey 

pub struct SortKey {
    pub metric: &'static str,
    pub descending: bool,
}

One key in a multi-key --sort-by spec. Names a metric from CTPROF_METRICS or CTPROF_DERIVED_METRICS and the sort direction for that key. Direction defaults to descending (largest delta first) so the common operator request — “show me the biggest regressions first” — is the unmarked form.

Fields

metric: &'static str

Metric name. Holds one of the CTPROF_METRICS or CTPROF_DERIVED_METRICS entries’ name fields verbatim — parse_sort_by looks up the input string in either registry and stores the matched &'static str, so this never carries an allocation. Equality against a registry name is by content (str::eq); both sides reference the same &'static str from the registry, so the byte-by-byte comparison succeeds in O(name.len()) without any heap access. The two registries are disjoint (the registry_and_derived_names_disjoint test pins this) so a metric value resolves unambiguously to one or the other.

descending: bool

True for descending (largest first), false for ascending (smallest first).

Trait Implementations

impl Clone for SortKey

fn clone(&self) -> SortKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SortKey

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

Formats the value using the given formatter.

impl PartialEq for SortKey

fn eq(&self, other: &SortKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
