Struct ConverterGraph 

pub struct ConverterGraph { /* private fields */ }

Converter graph with deterministic resolver.

use daedalus_data::convert::{ConverterBuilder, ConverterGraph};
use daedalus_data::model::{TypeExpr, Value, ValueType};

let mut graph = ConverterGraph::new();
graph.register(
    ConverterBuilder::new(
        "bool-id",
        TypeExpr::Scalar(ValueType::Bool),
        TypeExpr::Scalar(ValueType::Bool),
        |v: Value| Ok(v),
    )
    .build_boxed(),
);
let res = graph.resolve(&TypeExpr::Scalar(ValueType::Bool), &TypeExpr::Scalar(ValueType::Bool));
assert!(res.is_ok());

Implementations

impl ConverterGraph

pub fn new() -> Self

Create an empty converter graph.

pub fn register(&mut self, converter: Box<dyn Converter>)

Register a converter into the graph.

pub fn resolve( &self, from: &TypeExpr, to: &TypeExpr, ) -> DataResult<ConversionResolution>

Resolve a conversion path using default context.

pub fn resolve_with_context( &self, from: &TypeExpr, to: &TypeExpr, active_features: &[String], allow_gpu: bool, ) -> DataResult<ConversionResolution>

Resolve a conversion path with feature/GPU constraints.

Trait Implementations

impl Default for ConverterGraph

fn default() -> ConverterGraph

Returns the “default value” for a type.
