Struct icu_plurals::provider::PluralElementsPackedULE

pub struct PluralElementsPackedULE<V: VarULE + ?Sized> { /* private fields */ }

A bitpacked DST for PluralElements.

Can be put in a Cow or a [VarZeroSlice].

Implementations

impl<V> PluralElementsPackedULE<V>

where V: VarULE + ?Sized,

pub const unsafe fn from_bytes_unchecked(bytes: &[u8]) -> &Self

Casts a byte slice to a PluralElementsPackedULE.

Safety

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

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

Returns the value for the given PluralOperands and PluralRules.

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

Recovers the PluralElements corresponding to this packed structure.

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

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

Trait Implementations

impl<'a, V> Bake for &'a PluralElementsPackedULE<V>

where &'a V: Bake, V: VarULE + ?Sized,

fn bake(&self, ctx: &CrateEnv) -> TokenStream

Returns a TokenStream that would evaluate to self.

impl<'a, V> BakeSize for &'a PluralElementsPackedULE<V>

where &'a V: Bake, V: VarULE + ?Sized,

fn borrows_size(&self) -> usize

Returns the size

impl<V: Debug + VarULE + ?Sized> Debug for PluralElementsPackedULE<V>

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

Formats the value using the given formatter.

impl<'de, 'data, V> Deserialize<'de> for &'data PluralElementsPackedULE<V>

where V: VarULE + ?Sized, 'de: 'data,

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'de, V> Deserialize<'de> for Box<PluralElementsPackedULE<V>>

where V: VarULE + ?Sized, Box<V>: Deserialize<'de> + PartialEq + Debug,

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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()]

impl<V: PartialEq + VarULE + ?Sized> PartialEq for PluralElementsPackedULE<V>

fn eq(&self, other: &PluralElementsPackedULE<V>) -> 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<V> Serialize for PluralElementsPackedULE<V>

where V: PartialEq + Serialize + VarULE + ?Sized,

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<V: VarULE + ?Sized> ToOwned for PluralElementsPackedULE<V>

type Owned = Box<PluralElementsPackedULE<V>>

The resulting type after obtaining ownership.

fn to_owned(&self) -> Self::Owned

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.

impl<V> VarULE for PluralElementsPackedULE<V>

where V: VarULE + ?Sized,

fn validate_bytes(bytes: &[u8]) -> Result<(), UleError>

Validates a byte slice, &[u8].

unsafe fn from_bytes_unchecked(bytes: &[u8]) -> &Self

Takes a byte slice, &[u8], and return it as &Self with the same lifetime, assuming that this byte slice has previously been run through [Self::parse_bytes()] with success.

fn parse_bytes(bytes: &[u8]) -> Result<&Self, UleError>

Parses a byte slice, &[u8], and return it as &Self with the same lifetime.

fn as_bytes(&self) -> &[u8]

Given &Self, returns a &[u8] with the same lifetime.

fn to_boxed(&self) -> Box<Self>

Allocate on the heap as a Box<T>
