Crate camel_language_api 

camel-language-api — traits and types for building Camel expression languages.

Language SPI for rust-camel — defines the core traits all expression/predicate languages implement.

Main traits: Language, Expression, Predicate, MutatingExpression, MutatingPredicate. Main modules: error, eval, language_limits.

Modules

error

eval

Evaluation carriers: bind language expressions/predicates to trusted route-level metadata and transport evaluation failures as typed camel_api::CamelError::ExpressionFailed errors.

language_limits

Tunable resource limits for in-process scripting engines (Rhai, Boa JS).

Structs

ErrorPosition

1-based position inside the expression source text, as reported by the language engine. Not a route-definition position.

Exchange

An Exchange represents a message being routed through the framework.

Message

A message flowing through the Camel framework.

Enums

Body

The body of a message, supporting common payload types.

ExpressionErrorClass

Classification of a language-expression evaluation failure.

Traits

Expression

Evaluates to a Value against an Exchange.

Language

A Language factory: produces Expression and Predicate objects.

MutatingExpression

Expression that may modify the Exchange during evaluation. Changes to headers, properties, or body are propagated back.

MutatingPredicate

Predicate that may modify the Exchange during evaluation. Changes to headers, properties, or body are propagated back.

Predicate

Evaluates to bool against an Exchange.

Type Aliases

Value

Value type alias for dynamic header/property values.
