Get length of primitive object

pub const fn is_definite(&self) -> bool

Return true if length is definite

pub const fn assert_definite(&self) -> Result<()>

Return error if length is not definite

pub const fn assert_definite_inner(&self) -> Result<(), InnerError>

Return error if length is not definite

Trait Implementations

impl Add<Length> for usize

type Output = Length

The resulting type after applying the + operator.

fn add(self, rhs: Length) -> Self::Output

Performs the + operation.

impl Add<usize> for Length

type Output = Length

The resulting type after applying the + operator.

fn add(self, rhs: usize) -> Self::Output

Performs the + operation.

impl Add for Length

type Output = Length

The resulting type after applying the + operator.

fn add(self, rhs: Length) -> Self::Output

Performs the + operation.

impl AddAssign<usize> for Length

fn add_assign(&mut self, rhs: usize)

Performs the += operation.

impl AddAssign for Length

fn add_assign(&mut self, rhs: Length)

Performs the += operation.

impl Clone for Length

fn clone(&self) -> Length

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Length

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

Formats the value using the given formatter.

impl DynTagged for Length

fn tag(&self) -> Tag

Return the tag number of the object

fn accept_tag(_: Tag) -> bool

Return true if the tag number is acceptable for this object

fn class(&self) -> Class

Return the class of the object

fn constructed(&self) -> bool

Return true if the object is constructed

impl From<usize> for Length

fn from(l: usize) -> Self

Converts to this type from the input type.

impl Hash for Length

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 Length

fn eq(&self, other: &Length) -> 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<'a> Sum<&'a Length> for Length

fn sum<I: Iterator<Item = &'a Self>>(iter: I) -> Self

Takes an iterator and generates Self from the elements by “summing up” the items.

impl Sum for Length

fn sum<I: Iterator<Item = Self>>(iter: I) -> Self

Takes an iterator and generates Self from the elements by “summing up” the items.

impl Copy for Length

impl Eq for Length

impl StructuralPartialEq for Length
