Enum jni::signature::ReturnType

pub enum ReturnType {
    Primitive(Primitive),
    Object,
    Array,
}

Enum representing any java type that may be used as a return value

This type intentionally avoids capturing any heap allocated types (to avoid allocations while making JNI method calls) and so it doesn’t fully qualify the object or array types with a String like JavaType::Object does.

Trait Implementations

impl Clone for ReturnType

fn clone(&self) -> ReturnType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReturnType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ReturnType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for ReturnType

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq<ReturnType> for ReturnType

fn eq(&self, other: &ReturnType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
