Struct MultiByteChar

#[repr(C)]
pub struct MultiByteChar {
    pub pos: BytePos,
    pub bytes: u8,
}

Identifies an offset of a multi-byte character in a SourceFile

Fields

pos: BytePos

The absolute offset of the character in the SourceMap

bytes: u8

The number of bytes, >=2

Implementations

impl MultiByteChar

pub fn byte_to_char_diff(&self) -> u8

Computes the extra number of UTF-8 bytes necessary to encode a code point, compared to UTF-16 encoding.

1, 2, and 3 UTF-8 bytes encode into 1 UTF-16 char, but 4 UTF-8 bytes encode into 2.

Trait Implementations

impl Archive for MultiByteChar

where BytePos: Archive, u8: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedMultiByteChar

The archived representation of this type.

type Resolver = MultiByteCharResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl<__C: Fallible + ?Sized> CheckBytes<__C> for MultiByteChar

where <__C as Fallible>::Error: Trace, BytePos: CheckBytes<__C>, u8: CheckBytes<__C>,

unsafe fn check_bytes( value: *const Self, context: &mut __C, ) -> Result<(), <__C as Fallible>::Error>

Checks whether the given pointer points to a valid value within the given context.

impl Clone for MultiByteChar

fn clone(&self) -> MultiByteChar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MultiByteChar

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<MultiByteChar, __D> for Archived<MultiByteChar>

where BytePos: Archive, <BytePos as Archive>::Archived: Deserialize<BytePos, __D>, u8: Archive, <u8 as Archive>::Archived: Deserialize<u8, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<MultiByteChar, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for MultiByteChar

fn eq(&self, other: &MultiByteChar) -> 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<__S: Fallible + ?Sized> Serialize<__S> for MultiByteChar

where BytePos: Serialize<__S>, u8: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
