Struct ReportParam 

pub struct ReportParam {
    pub name: String,
    pub default: Option<Value>,
    pub db_type: Option<String>,
    pub rule: ValidationRule,
}

A single named parameter of a report. Reuses the entity ValidationRule engine (flattened into this struct) so required/allowed/minimum/pattern/format/etc. all apply to the value the caller supplies at run time. default is applied when the param is absent.

Fields

name: String

default: Option<Value>

Value used when the caller omits this param. Ignored when the param is required.

db_type: Option<String>

Optional SQL cast applied to the bound value (e.g. “timestamptz”, “int”, “uuid”). All params bind as TEXT, so numeric/temporal params need a cast to compare correctly.

rule: ValidationRule
