Struct TryCatch

pub struct TryCatch<This, J>
where
    This: JvmOp,
    J: Upcast<Throwable>,
{ /* private fields */ }

Trait Implementations

impl<This, J> Clone for TryCatch<This, J>

where This: JvmOp, J: Upcast<Throwable>,

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<This, J> JvmOp for TryCatch<This, J>

where This: JvmOp, J: Upcast<Throwable>,

type Output<'jvm> = Result<<This as JvmOp>::Output<'jvm>, Local<'jvm, J>>

fn do_jni<'jvm>( self, jvm: &mut Jvm<'jvm>, ) -> LocalResult<'jvm, Self::Output<'jvm>>

Internal method

fn assert_not_null<T>(self) -> NotNull<Self>

where T: JavaObject, for<'jvm> Self: JvmOp<Output<'jvm> = Option<Local<'jvm, T>>>,

fn upcast<To>(self) -> AsUpcast<Self, To>

where for<'jvm> Self::Output<'jvm>: AsJRef<To>, To: JavaObject,

Most duchess-wrapped Java objects will automatically be able to call all methods defined on any of its super classes or interfaces it implements, but this can be used to “force” the output of the operation to be typed as an explicit super type To.

fn catch<J>(self) -> TryCatch<Self, J>

where J: Upcast<Throwable>,

fn execute<R>(self) -> Result<R>

where for<'jvm> Self::Output<'jvm>: IntoRust<R>,

Execute on the JVM, starting a JVM instance if necessary.

fn execute_with<'jvm, R>(self, jvm: &mut Jvm<'jvm>) -> LocalResult<'jvm, R>

where for<'j> Self::Output<'j>: IntoRust<R>,

Internal method

impl<This, J> Copy for TryCatch<This, J>

where This: JvmOp + Copy, J: Upcast<Throwable>,
