Enum Detail 

#[repr(u8)]
pub enum Detail {
    Off = 0,
    Stages = 1,
    Diagnostic = 2,
}

How much performance measurement this process performs.

Variants

Off = 0

Measure nothing. No clock is read on any hot path.

Stages = 1

Record fixed stage spans, typed counters, and the causal record.

Diagnostic = 2

Everything in Detail::Stages, plus the per-pattern, per-decoder and per-backend decomposition that costs measurable hot-path time.

Implementations

impl Detail

pub const fn as_str(self) -> &'static str

Stable text label used by human reports and config echoes.

pub const fn records_stages(self) -> bool

True when stage spans and typed counters should be recorded.

pub const fn is_diagnostic(self) -> bool

True when the expensive per-pattern and per-backend decomposition should be recorded.

Trait Implementations

impl Clone for Detail

fn clone(&self) -> Detail

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Detail

impl Debug for Detail

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

Formats the value using the given formatter.

impl Default for Detail

fn default() -> Detail

Returns the “default value” for a type.

impl Eq for Detail

impl Hash for Detail

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Detail

fn cmp(&self, other: &Detail) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Detail

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Detail

fn partial_cmp(&self, other: &Detail) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
