Struct Utf8Parser 

pub struct Utf8Parser { /* private fields */ }

Implementations

impl Utf8Parser

pub fn new(alignment: Alignment, trim_symbol: Symbol) -> Self

pub fn try_parse<'a>( &self, bytes: &'a [u8], n_runes: usize, ) -> (usize, Option<&'a str>)

Try and parse the byte slice as UTF-8 characters and count the number of bytes that the boolean was represented as in the byte slice.

Safety

This function utilizes the from_utf8_unchecked function to convert the byte slice to a string representation. This method is inherently unsafe and might cause the program to panic. We have to assume that the input bytes are valid UTF-8, because recovering from the situation where the bytes were not valid UTF-8 is not possible since then we don’t know how far into the buffer we need to read.

Performance

The function from_utf8_unchecked will put the string slice on the stack and not perform any heap allocations. As such, we need to know the lifetimes of it.
