Function hcl::from_str

pub fn from_str<'de, T>(s: &'de str) -> Result<T>
where
    T: Deserialize<'de>,

Deserialize an instance of type T from a string of HCL text.

By default, the deserialization will follow the HCL JSON Specification.

If preserving HCL semantics is required consider deserializing into a Body instead or use hcl::parse to directly parse the input into a Body.

Example

use serde_json::{json, Value};

let input = r#"
    some_attr = {
      foo = [1, 2]
      bar = true
    }

    some_block "some_block_label" {
      attr = "value"
    }
"#;

let expected = json!({
    "some_attr": {
        "foo": [1, 2],
        "bar": true
    },
    "some_block": {
        "some_block_label": {
            "attr": "value"
        }
    }
});

let value: Value = hcl::from_str(input)?;

assert_eq!(value, expected);

Errors

This functions fails with an error if the data does not match the structure of T.
