Enum Layer 

pub enum Layer {
    Builtin,
    ImportedFile,
    WholeExpression,
}

Which delegation boundary was crossed.

Variants

Builtin

A builtin with no native VM implementation went to the tree-walker. Architectural — counted, never fatal.

ImportedFile

An imported file failed to compile or to run, and the tree-walker evaluated it instead. Fatal under strict.

WholeExpression

The whole top-level expression failed and was re-run on the tree-walker. Fatal under strict.

Implementations

impl Layer

pub const ALL: &'static [Layer]

Every layer, so a caller can report totals without hand-listing — and so a new layer cannot be added without appearing in the report.

pub fn name(self) -> &'static str

pub fn is_fatal_under_strict(self) -> bool

Whether strict mode refuses this layer.
