Variants

Void

Boolean

Char

Byte

Short

Int

Float

Long

Double

Array(Box<Type>)

Array type, with the element type (which may itself be an array).

Implementations

impl Type

pub const VOID_TYPE: Type = Type::Void

pub const BOOLEAN_TYPE: Type = Type::Boolean

pub const CHAR_TYPE: Type = Type::Char

pub const BYTE_TYPE: Type = Type::Byte

pub const SHORT_TYPE: Type = Type::Short

pub const INT_TYPE: Type = Type::Int

pub const FLOAT_TYPE: Type = Type::Float

pub const LONG_TYPE: Type = Type::Long

pub const DOUBLE_TYPE: Type = Type::Double

pub fn get_type(descriptor: &str) -> Self

Returns the Type corresponding to the given field or method descriptor.

Panics

Panics if the descriptor is invalid.

pub fn get_object_type(internal_name: &str) -> Self

Returns the Type corresponding to the given internal name. If the name starts with '[', it is treated as an array descriptor.

pub fn get_method_type(descriptor: &str) -> Self

Returns the method Type corresponding to the given method descriptor.

Panics

Panics if the descriptor is not a valid method descriptor.

pub fn get_method_type_from_parts( return_type: Type, argument_types: Vec<Type>, ) -> Self

Creates a method type from its return type and argument types.

pub fn get_sort(&self) -> u8

Returns the sort of this type (as an integer, compatible with ASM constants).

pub fn get_descriptor(&self) -> String

Returns the descriptor of this type.

pub fn get_class_name(&self) -> String

Returns the Java class name corresponding to this type (e.g. “int”, “java.lang.Object[]”).

pub fn internal_name(&self) -> Option<String>

Returns the internal name of this type. For object types, this is the internal name (e.g. "java/lang/Object"). For array types, this is the descriptor itself (e.g. "[I"). For other types, returns None.

pub fn get_dimensions(&self) -> usize

If this is an array type, returns the number of dimensions. Otherwise returns 0.

pub fn get_element_type(&self) -> Option<&Type>

If this is an array type, returns the element type (which may itself be an array). Otherwise returns None.

pub fn get_argument_types(&self) -> Option<&[Type]>

If this is a method type, returns the argument types.

pub fn get_return_type(&self) -> Option<&Type>

If this is a method type, returns the return type.

pub fn get_size(&self) -> usize

Returns the size of values of this type (1 for most, 2 for long/double, 0 for void).

pub fn get_argument_count(&self) -> usize

Returns the number of arguments of this method type. Panics if called on a non-method type.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl Display for Type

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

Formats the value using the given formatter.

impl Hash for Type

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 Type

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