Implementations§

source§

impl<V> PluralElementsPackedULE<V>
where V: VarULE + ?Sized,

source

pub const unsafe fn from_byte_slice_unchecked( bytes: &[u8], ) -> &PluralElementsPackedULE<V>

Casts a byte slice to a PluralElementsPackedULE.

§Safety

The bytes must be valid according to PluralElementsPackedULE::validate_byte_slice.

source

pub fn get<'a>( &'a self, op: PluralOperands, rules: &PluralRules, ) -> (FourBitMetadata, &'a V)

Returns the value for the given PluralOperands and PluralRules.

source

pub fn decode(&self) -> PluralElements<(FourBitMetadata, &V)>

Recovers the PluralElements corresponding to this packed structure.

source

pub fn get_default(&self) -> (FourBitMetadata, &V)

Returns the value for the default (“other”) plural variant.
