Struct quoted_string::spec::PartialCodePoint [−][src]
pub struct PartialCodePoint(_);
A type which represents part of a utf-8 code point
It does not know which part of a code point it represents (e.g. utf-8 first or later byte of a code point > 0x7f).
When used in a iteration like context it is also not guaranteed to go through all utf-8 bytes, it might, or it might just represent the first byte replacing all bytes > 0x7f with 0xFF.
This allows efficiently abstracting over char sequences and utf-8 byte sequences for tasks which are mainly focused on us-ascii and treat all non ascii utf8 code points the same.
Methods
impl PartialCodePoint
[src]
impl PartialCodePoint
pub fn as_u8(self) -> u8
[src]
pub fn as_u8(self) -> u8
pub fn from_utf8_byte(u8b: u8) -> PartialCodePoint
[src]
pub fn from_utf8_byte(u8b: u8) -> PartialCodePoint
creates a partial code point from a utf8 byte
The inner value will be the byte passed in, which should not be 0xff as 0xff doesn't appear in a utf-8 byte sequence
Debug Assertions
if debug assertions are enabled and 0xff is passed in this will panic as it wasn't created from a byte from a utf-8 byte sequence
pub fn from_code_point(code_point: u32) -> PartialCodePoint
[src]
pub fn from_code_point(code_point: u32) -> PartialCodePoint
creates a PartialCodePoint
from a utf-8 code point.
The inner value will be:
- the char if the code point is us-ascii
- 0xFF if it is larger then 0x7f i.e. non us-ascii
