Enum InvocationTarget 

pub enum InvocationTarget {
    MastRoot(Span<Word>),
    Symbol(Ident),
    Path(Span<Arc<Path>>),
}

Describes targets of exec, call, and syscall instructions.

A label of an invoked procedure must comply with the following rules:

• It can be a hexadecimal string representing a MAST root digest ([Word]). In this case, the label must start with “0x” and must be followed by a valid hexadecimal string representation of an [Word].
• It can contain a single procedure name. In this case, the label must comply with procedure name rules.
• It can contain module name followed by procedure name (e.g., “module::procedure”). In this case both module and procedure name must comply with relevant name rules.

All other combinations will result in an error.

Variants

MastRoot(Span<Word>)

An absolute procedure reference, but opaque in that we do not know where the callee is defined. However, it does not actually matter, we consider such references to be a priori valid.

Symbol(Ident)

A locally-defined procedure.

Path(Span<Arc<Path>>)

An externally-defined procedure.

Implementations
