Struct AdContextBuilder 

pub struct AdContextBuilder { /* private fields */ }

Builder for AdContext.

Examples

use tenferro_ad::AdContextBuilder;

let ad = AdContextBuilder::new().build().unwrap();
assert!(ad
    .semantic_extension_rules()
    .lookup_linearize("example.missing.v1")
    .is_none());

Implementations

impl AdContextBuilder

pub fn new() -> Self

Create an empty builder.

Examples

use tenferro_ad::AdContextBuilder;

let _builder = AdContextBuilder::new();

pub fn with_semantic_extension_rules( self, rules: SemanticExtensionRuleSet, ) -> Result<Self, SemanticExtensionRegistryError>

Include an owned semantic-program extension AD rule set.

Errors

Returns SemanticExtensionRegistryError::MalformedFamilyId when a family identifier is invalid, or SemanticExtensionRegistryError::DuplicateRule when the same family and role were already supplied.

pub fn build(self) -> Result<AdContext, Infallible>

Build the context.

Semantic extension rules have already been validated and merged by Self::with_semantic_extension_rules.

Examples

use tenferro_ad::AdContext;

let ad = AdContext::builder().build().unwrap();
assert!(ad
    .semantic_extension_rules()
    .lookup_linearize("example.missing.v1")
    .is_none());

Errors

The error type is std::convert::Infallible, so this finalization step never returns Err after semantic rule registration. It retains a Result so callers can compose it with the fallible registration step.

Trait Implementations

impl Clone for AdContextBuilder

fn clone(&self) -> AdContextBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AdContextBuilder

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

impl Default for AdContextBuilder

fn default() -> AdContextBuilder
