Implementations

impl ShapeRef

pub fn is_signed_integer(&self) -> bool

Return whether this is a signed integer shape.

pub fn is_unsigned_integer(&self) -> bool

Return whether this is an unsigned integer shape.

pub fn is_integer(&self) -> bool

Return whether this is any integer shape.

pub fn is_float(&self) -> bool

Return whether this is a floating point shape.

pub fn is_number(&self) -> bool

Return whether this is any numeric shape.

Trait Implementations

impl Clone for ShapeRef

fn clone(&self) -> ShapeRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeRef

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

Formats the value using the given formatter.

impl Eq for ShapeRef

impl PartialEq for ShapeRef

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