Struct ParamStats 

pub struct ParamStats {
    pub count: u32,
    pub length_dist: Distribution,
    pub numeric_dist: Distribution,
    pub type_counts: HashMap<String, u32>,
}

Detailed statistics for a parameter value.

Fields

count: u32

Frequency count

length_dist: Distribution

String length distribution

numeric_dist: Distribution

Numeric value distribution (if applicable)

type_counts: HashMap<String, u32>

Type counts

Implementations

impl ParamStats

pub fn new() -> Self

pub fn update(&mut self, value: &str)

Update statistics with a new value.

Type categories are bounded to prevent memory exhaustion attacks where an attacker sends many values designed to create unique type categories.

pub fn update_with_limit(&mut self, value: &str, max_type_counts: usize)

Update with configurable type count limit.

Trait Implementations

impl Clone for ParamStats

fn clone(&self) -> ParamStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamStats

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

Formats the value using the given formatter.

impl Default for ParamStats

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ParamStats

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ParamStats

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

where __S: Serializer,
