Trait Implementations

impl AsULE for LineBreak

type ULE = LineBreakULE

The ULE type corresponding to Self.

fn to_unaligned(self) -> Self::ULE

Converts from Self to Self::ULE.

fn from_unaligned(unaligned: Self::ULE) -> Self

Converts from Self::ULE to Self.

impl Clone for LineBreak

fn clone(&self) -> LineBreak

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineBreak

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

Formats the value using the given formatter.

impl Hash for LineBreak

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 Ord for LineBreak

fn cmp(&self, other: &LineBreak) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LineBreak

fn eq(&self, other: &LineBreak) -> 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 PartialOrd for LineBreak

fn partial_cmp(&self, other: &LineBreak) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TrieValue for LineBreak

type TryFromU32Error = TryFromIntError

Last-resort fallback value to return if we cannot read data from the trie.

fn try_from_u32(i: u32) -> Result<Self, Self::TryFromU32Error>

A parsing function that is primarily motivated by deserialization contexts. When the serialization type width is smaller than 32 bits, then it is expected that the call site will widen the value to a u32 first.

fn to_u32(self) -> u32

A method for converting back to a u32 that can roundtrip through Self::try_from_u32(). The default implementation of this trait method panics in debug mode and returns 0 in release mode.

impl<'a> ZeroMapKV<'a> for LineBreak

type Container = ZeroVec<'a, LineBreak>

The container that can be used with this type: ZeroVec or VarZeroVec.

type Slice = ZeroSlice<LineBreak>

type GetType = LineBreakULE

The type produced by Container::get()

type OwnedType = LineBreak

The type produced by Container::replace() and Container::remove(), also used during deserialization. If Self is human readable serialized, deserializing to Self::OwnedType should produce the same value once passed through Self::owned_as_self()

impl Copy for LineBreak

impl Eq for LineBreak

impl StructuralPartialEq for LineBreak

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
