Struct DescriptorBuilder 

pub struct DescriptorBuilder { /* private fields */ }

Builder to construct descriptors with deterministic ordering.

use daedalus_data::descriptor::{DescriptorBuilder, GpuHints, MemoryLocation};
use daedalus_data::errors::DataResult;
use daedalus_data::model::{TypeExpr, Value, ValueType};

fn build_descriptor() -> DataResult<()> {
    let desc = DescriptorBuilder::new("example", "1.0.0")
        .label("Example")
        .settable(true)
        .type_expr(TypeExpr::Scalar(ValueType::String))
        .default(Value::String("hi".into()))
        .codec("json")
        .feature_flag("core")
        .gpu_hints(GpuHints { requires_gpu: false, preferred_memory: Some(MemoryLocation::Host) })
        .build()?;
