Struct CrossDomainMapper 

pub struct CrossDomainMapper { /* private fields */ }

Translates ternary patterns between different domains.

Domains are identified by string names. Each domain has a mapping that interprets ternary values in its own context.

Implementations

impl CrossDomainMapper

pub fn new() -> Self

pub fn register_domain( &mut self, name: &str, negative_label: &str, zero_label: &str, positive_label: &str, )

Register a domain with its ternary value interpretations.

pub fn translate( &self, pattern: &Pattern, from_domain: &str, to_domain: &str, ) -> Option<Vec<String>>

Translate a pattern from one domain’s interpretation to another’s. The ternary values stay the same; only the labels change.

pub fn label_for(&self, domain: &str, value: Ternary) -> Option<&str>

Get the label for a value in a specific domain.

pub fn domain_names(&self) -> Vec<&str>

List registered domain names.

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

Performs copy-assignment from source.

impl Debug for CrossDomainMapper

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