Struct marked_yaml::FromNodeError

pub struct FromNodeError { /* private fields */ }

Available on crate feature serde only.

The error returned by from_node

From here you can get the logical path to the error if one is available, and then via the error: the marker indicating where the error occurred if it’s available. Finally you may extract the error itself.

Implementations

impl FromNodeError

pub fn path(&self) -> Option<&str>

Available on crate feature serde-path only.

The logical path representing where the error occurred.

Note: this likely will only ever be Some(value) if you enable the serde-path feature, though the function itself will be available with the serde feature.

pub fn into_inner(self) -> Error

Extract the inner error

Methods from Deref<Target = Error>

pub fn start_mark(&self) -> Option<Marker>

Retrieve the start marker if there is one

Most spans which are generated by the loader only have start marks (containers have end marks as well, but these failures) are unlikely to exist here.

const YAML: &str = r#"
bad: float
"#;

#[derive(Deserialize)]
struct Example {
    bad: Spanned<f64>,
}

let nodes = parse_yaml(0, YAML).unwrap();
let err = from_node::<Example>(&nodes).err().unwrap();

assert!(matches!(&*err, Error::FloatParseFailure(_,_)));

let mark = err.start_mark().unwrap();

assert_eq!(mark.source(), 0);
assert_eq!(mark.line(), 2);
assert_eq!(mark.column(), 6);
