Struct ConstraintOptions 

pub struct ConstraintOptions {
    pub operator: Option<LogicalOperator>,
    pub threshold: Option<f64>,
    pub flags: HashMap<String, bool>,
    pub options: HashMap<String, String>,
}

Common options for constraint configuration.

This struct provides a builder pattern for common constraint options that can be extended by specific constraint types.

Fields

operator: Option<LogicalOperator>

The logical operator for multi-column constraints

threshold: Option<f64>

Threshold value (interpretation depends on constraint type)

flags: HashMap<String, bool>

Additional boolean flags

options: HashMap<String, String>

Additional string options

Implementations

impl ConstraintOptions

pub fn new() -> Self

Creates a new options builder.

pub fn with_operator(self, operator: LogicalOperator) -> Self

Sets the logical operator.

pub fn with_threshold(self, threshold: f64) -> Self

Sets the threshold value.

pub fn with_flag(self, name: impl Into<String>, value: bool) -> Self

Sets a boolean flag.

pub fn with_option( self, name: impl Into<String>, value: impl Into<String>, ) -> Self

Sets a string option.

pub fn operator_or(&self, default: LogicalOperator) -> LogicalOperator

Returns the operator or a default value.

pub fn threshold_or(&self, default: f64) -> f64

Returns the threshold or a default value.

pub fn flag(&self, name: &str) -> bool

Returns a flag value or false if not set.

pub fn option(&self, name: &str) -> Option<&str>

Returns an option value.
