Enum ResolutionWarning 

pub enum ResolutionWarning {
    InsufficientResolution {
        unique_values: usize,
        total_samples: usize,
        zero_fraction: f64,
        timer_resolution_ns: f64,
    },
    HighQuantization {
        unique_values: usize,
        total_samples: usize,
    },
}

Warning from the resolution check.

Variants

InsufficientResolution

Timer resolution is too coarse for the operation being measured.

Severity: ResultUndermining

The statistical analysis will be unreliable because most measurements are quantized to the same few values.

Fields

unique_values: usize

Number of unique timing values observed.

total_samples: usize

Total number of samples.

zero_fraction: f64

Fraction of samples that were exactly zero.

timer_resolution_ns: f64

Estimated timer resolution in nanoseconds.

HighQuantization

Many samples have identical timing values.

Severity: Informational

This may indicate quantization effects from coarse timer resolution, but the statistical analysis is still valid.

Fields

unique_values: usize

Number of unique timing values observed.

total_samples: usize

Total number of samples.

Implementations

impl ResolutionWarning

pub fn is_result_undermining(&self) -> bool

Check if this warning undermines result confidence.

pub fn severity(&self) -> PreflightSeverity

Get the severity of this warning.

pub fn description(&self) -> String

Get a human-readable description of the warning.

pub fn guidance(&self) -> Option<String>

Get guidance for addressing this warning.

Note: This provides generic guidance. For context-aware recommendations (e.g., based on timer fallback reason), see the output formatting layer.

pub fn to_warning_info(&self) -> PreflightWarningInfo

Convert to a PreflightWarningInfo.

Trait Implementations

impl Clone for ResolutionWarning

fn clone(&self) -> ResolutionWarning

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolutionWarning

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ResolutionWarning

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ResolutionWarning

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
