Enum ErrorKind 

pub enum ErrorKind {
    Syntax(Syntax),
    Ambiguous(Syntax),
    Limit(Limit),
    Resource(MemoryError),
    Unsupported(Unsupported),
    Foreign,
}

Independent failure classes; processing causes cannot become syntax faults.

Variants

Syntax(Syntax)

Unreadable syntax with its actual domain and range.

Ambiguous(Syntax)

Two incompatible readings; selecting the first would lose meaning.

Limit(Limit)

Caller-selected resource count exhausted before the operation.

Resource(MemoryError)

Actual shared allocator, capacity, or current/source work refusal.

Unsupported(Unsupported)

Required capability is explicitly unavailable.

Foreign

A caller mixed source/session/document identities.
