Enum Problem 

pub enum Problem {
    Syntax {
        path: Vec<Seg>,
        error: Syntax,
    },
    Unresolved {
        path: Vec<Seg>,
        reference: String,
    },
    NotStringifiable {
        path: Vec<Seg>,
        reference: String,
        kind: &'static str,
    },
}

One thing wrong with one reference.

Variants

Syntax

A reference that is not spelled like one.

Fields

path: Vec<Seg>

error: Syntax

Unresolved

A reference that names nothing: a key the merged document does not have, or a variable the environment does not set.

An error rather than a pass-through. Leaving ${db.hostname} in the output would ship a typo as a literal, and the document is already the authority on what exists.

Fields

path: Vec<Seg>

reference: String

NotStringifiable

A container or a null in embedded position — url = "http://${db}/".

Legal in whole-string position, where it aliases the subtree. Embedded it has no format-independent rendering, so it is rejected in v1.

Fields

path: Vec<Seg>

reference: String

kind: &'static str
