Struct Stats 

#[non_exhaustive]
pub struct Stats { /* private fields */ }

The Nom metric suite.

Implementations

impl Stats

pub fn merge(&mut self, other: &Stats)

Merges a second Nom metric suite into the first one

pub fn functions(&self) -> u64

Counts the number of function definitions in a scope

pub fn closures(&self) -> u64

Counts the number of closures in a scope

pub fn functions_sum(&self) -> u64

Return the sum metric for functions

pub fn closures_sum(&self) -> u64

Return the sum metric for closures

pub fn functions_average(&self) -> f64

Returns the average number of function definitions over all spaces.

nom’s averages are per space (space_count). The .max(1) guard keeps a space-less aggregate from dividing by zero (space_count defaults to 1 and only grows, so today it is a no-op, but the guard removes the reliance on that invariant — cf. the divisor guards added for #428).

pub fn closures_average(&self) -> f64

Returns the average number of closures over all spaces.

pub fn average(&self) -> f64

Returns the average number of function definitions and closures over all spaces.

pub fn functions_min(&self) -> u64

Counts the number of function definitions in a scope.

Collapses the usize::MAX sentinel that Stats::default() plants into functions_min to 0.0, so a never-observed space serializes to a meaningful number rather than 1.8446744e19.

pub fn closures_min(&self) -> u64

Counts the number of closures in a scope.

Same usize::MAX sentinel collapse as functions_min.

pub fn functions_max(&self) -> u64

Counts the number of function definitions in a scope

pub fn closures_max(&self) -> u64

Counts the number of closures in a scope

pub fn total(&self) -> u64

Returns the total number of function definitions and closures in a scope

Trait Implementations

impl Clone for Stats

fn clone(&self) -> Stats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stats

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

Formats the value using the given formatter.

impl Default for Stats

fn default() -> Self

Returns the “default value” for a type.

impl Display for Stats

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

Formats the value using the given formatter.

impl From<&Stats> for Nom

fn from(s: &Stats) -> Self

Converts to this type from the input type.

impl PartialEq for Stats

fn eq(&self, other: &Stats) -> 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.

impl Serialize for Stats

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
