Struct Signature 

pub struct Signature { /* private fields */ }

Provides strongly-typed JVM type signature strings at compile-time

A Signature can be obtained for all Type via Signature::of:

use toad_jni::java;

assert_eq!(java::Signature::of::<i32>().as_str(), "I");
assert_eq!(java::Signature::of::<()>().as_str(), "V");

type SumBigInts = fn(Vec<java::math::BigInteger>) -> java::math::BigInteger;
assert_eq!(java::Signature::of::<SumBigInts>().as_str(),
           "([Ljava/math/BigInteger;)Ljava/math/BigInteger;");

Implementations

impl Signature

pub const fn of<T>() -> Self

where T: Type,

Get the Signature instance for type T

pub fn return_type(self) -> ReturnType

Get the jni::signature::ReturnType of a function Signature

pub fn as_str(&self) -> &str

Convert a Signature reference to str

Trait Implementations

impl AsRef<str> for Signature

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl Display for Signature

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

Formats the value using the given formatter.

impl Ord for Signature

fn cmp(&self, other: &Signature) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Signature

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Signature

fn partial_cmp(&self, other: &Signature) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for Signature

impl Eq for Signature

impl StructuralPartialEq for Signature
