Crate prebindgen_jni_runtime 

Runtime half of the JNI binding generator.

prebindgen’s lang::JniGen adapter generates JNI binding code at build time; the helpers in this crate are what that generated code calls at run time. A shipped binding library depends on this crate, not on the generator.

Structs

CachedIfaceMethod

A (pinned interface class, method ID) pair resolved once per process. Declare as static; the embedded OnceLock handles the one-time resolution race (both winners produce equivalent values).

Enums

JniBindingError

Framework error type for the JNI binding’s error channel. T is the function’s domain error (() for the E-agnostic framework converters, whose failures are always Self::JniError).
