Enum DataLen 

pub enum DataLen<Index> {
    Known(Index),
    LBound(Index),
}

Result of Self::len

Variants

Known(Index)

Length is known and specified exactly

LBound(Index)

A lower bound on length is specified

Implementations

impl<Index: Copy> DataLen<Index>

pub fn len(&self) -> Index

Returns the length payload (known or lower bound)

pub fn is_known(&self) -> bool

Returns true if a known length given

Trait Implementations

impl<Index: Clone> Clone for DataLen<Index>

fn clone(&self) -> DataLen<Index>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Index: Debug> Debug for DataLen<Index>

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

Formats the value using the given formatter.

impl<Index: PartialEq> PartialEq for DataLen<Index>

fn eq(&self, other: &DataLen<Index>) -> 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.
