Enum Outcome 

pub enum Outcome {
    Syntax {
        offset: usize,
        kind: String,
    },
    Parse(String),
    Expr {
        ast: String,
        run: Run,
    },
    Module(Result<Run, String>),
}

How one run of a source ended. Each kind maps to one shape of the JSON described in the module docs. The stage there mirrors the pipeline vocabulary: syntax (the Muon layer), parse (Muon tree → Elly AST), load (a module graph), eval (a raise that unwound to the top level).

Variants

Syntax

The syntax layer (Muon) rejected the source.

Fields

offset: usize

kind: String

Parse(String)

Neither an expression nor a module.

Expr

An expression ran. ast is its tagged JSON dump.

Fields

ast: String

run: Run

Module(Result<Run, String>)

A module’s __main ran, or the module would not load, which includes having no __main. A library is reported as the latter, so it never appears as Run::Library here.

Implementations

impl Outcome

pub fn to_json(&self) -> String

The JSON elly_run hands the page.
