passto

Passto is a term with no single, universal definition in technology. Depending on context, it may refer to a product name, a brand, or simply the verb phrase “pass to,” indicating transfer from one component to another. In computing, passto is often used to describe mechanisms or patterns that hand off data, control, or execution context from one part of a system to a downstream recipient.

Common applications include data piping in software pipelines, middleware that forwards requests to subsequent services, and delegation patterns where a caller hands off responsibility to a callee. In event-driven architectures, passto describes the act of routing an event or message to a consumer that will process it further. The emphasis is on the act of passing rather than the precise data format, and implementations can span synchronous and asynchronous communication models.

Etymologically, passto combines pass and to, reflecting the directional transfer inherent in the concept. The term is not standardized and may appear in product names, library documentation, or in informal discussions, often alongside related terms such as passthrough, propagation, and delegation.

Because passto lacks a formal definition, readers should rely on the specific context to understand its meaning in a given source. See also passthrough, data routing, and delegation patterns.
