Implementations

impl JvmType

pub fn descriptor(&self) -> String

Returns the JVM field descriptor string (e.g. "I", "[Ljava/lang/String;").

pub fn slot_size(&self) -> usize

Returns the size in JVM local-variable / stack slots (1 or 2).

pub fn is_wide(&self) -> bool

true for the two “wide” primitive types (Long, Double).

pub fn is_reference(&self) -> bool

true for reference types (Object, Array, Generic).

pub fn is_int_category(&self) -> bool

true for integer-category types (Byte, Short, Int, Boolean, Char).

Trait Implementations

impl Clone for JvmType

fn clone(&self) -> JvmType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JvmType

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

Formats the value using the given formatter.

impl Display for JvmType

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

Formats the value using the given formatter.

impl Hash for JvmType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for JvmType

fn eq(&self, other: &JvmType) -> 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.
