Struct jni::objects::JFieldID

#[repr(C)]
pub struct JFieldID<'a> { /* fields omitted */ }

Wrapper around sys::jfieldid that adds a lifetime. This prevents it from outliving the context in which it was acquired and getting GC'd out from under us. It matches C's representation of the raw pointer, so it can be used in any of the extern function argument positions that would take a jfieldid.

Methods

impl<'a> JFieldID<'a>

pub fn into_inner(self) -> jfieldID

Unwrap to the internal jni type.

Trait Implementations
