pub fn explicit_zero(&self) -> Option<&T>

The value used when the PluralOperands are exactly 0.

pub fn explicit_one(&self) -> Option<&T>

The value used when the PluralOperands are exactly 1.

pub fn map<B, F: Fn(T) -> B>(self, f: F) -> PluralElements<B>

Applies a function f to map all values to another type.

impl<T: PartialEq> PluralElements<T>

pub fn with_zero_value(self, zero: Option<T>) -> Self

Trait Implementations

impl<T: Debug> Debug for PluralElements<T>

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

Formats the value using the given formatter.

impl<T, V> EncodeAsVarULE<PluralElementsPackedULE<V>> for PluralElements<(FourBitMetadata, T)>

where T: PartialEq + Debug, for<'a> &'a T: EncodeAsVarULE<V>, V: VarULE + ?Sized,

fn encode_var_ule_as_slices<R>(&self, _cb: impl FnOnce(&[&[u8]]) -> R) -> R

Calls cb with a piecewise list of byte slices that when concatenated produce the memory pattern of the corresponding instance of T.

fn encode_var_ule_len(&self) -> usize

Return the length, in bytes, of the corresponding [VarULE] type

fn encode_var_ule_write(&self, dst: &mut [u8])

Write the corresponding [VarULE] type to the dst buffer. dst should be the size of [Self::encode_var_ule_len()]

where V: VarULE + ?Sized, T: PartialEq + Debug, for<'a> &'a T: EncodeAsVarULE<V>,

fn from(value: PluralElements<T>) -> Self

Converts to this type from the input type.
