Struct icu_casemap::provider::exception_helpers::SlotPresence

#[repr(transparent)]
pub struct SlotPresence(pub u8);

Packed slot presence marker

All bits are valid, though bit 4 is unused and reserved

Bits:

              0: Lowercase mapping (code point)
              1: Case folding (code point)
              2: Uppercase mapping (code point)
              3: Titlecase mapping (code point)
              4: Delta to simple case mapping (code point) (sign stored separately)
              5: RESERVED
              6: Closure mappings (string; see below)
              7: Full mappings (strings; see below)

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. While the serde representation of data structs is guaranteed to be stable, their Rust representation might not be. Use with caution.

Implementations

impl SlotPresence

pub(crate) fn add_slot(&mut self, slot: ExceptionSlot)

pub(crate) fn has_slot(self, slot: ExceptionSlot) -> bool

Trait Implementations

impl AsULE for SlotPresence

type ULE = SlotPresence

The ULE type corresponding to Self.

fn from_unaligned(u: Self) -> Self

Converts from Self::ULE to Self.

fn to_unaligned(self) -> Self

Converts from Self to Self::ULE.

impl Clone for SlotPresence

fn clone(&self) -> SlotPresence

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SlotPresence

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

Formats the value using the given formatter.

impl Default for SlotPresence

fn default() -> SlotPresence

Returns the “default value” for a type.

impl PartialEq for SlotPresence

fn eq(&self, other: &SlotPresence) -> 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 ULE for SlotPresence

fn validate_byte_slice(bytes: &[u8]) -> Result<(), ZeroVecError>

Validates a byte slice, &[u8].

fn parse_byte_slice(bytes: &[u8]) -> Result<&[Self], ZeroVecError>

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

unsafe fn from_byte_slice_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_byte_slice() with success.

fn as_byte_slice(slice: &[Self]) -> &[u8]

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