Enum ArmLabel 

pub enum ArmLabel {
    Ok,
    Error,
    Wildcard,
    Pattern(String),
}

Which arm of a Branch node a branch edge belongs to.

A case over a workflow primitive’s Result has an Ok(..) arm (the success continuation) and an Error(..) arm (the compensation / failure continuation). A case over another subject the walker recurses through (a decode, a guard) labels each arm by its leading constructor, or ArmLabel::Wildcard for a _ catch-all.

Variants

Ok

The Ok(..) arm — the success continuation.

Error

The Error(..) arm — the failure / compensation continuation.

Wildcard

A _ catch-all arm.

Pattern(String)

Any other arm, labelled by its leading pattern constructor.
