You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: text.rs
    path of file: ./repos/readyset/readyset-data/src
    
    the code of the file until where you have to start completion: use std::cmp::Ordering;
use std::convert::{TryFrom, TryInto};
use std::fmt;
use std::num::{IntErrorKin
    
    pub fn from_slice(v: &[u8]) -> Result<Self, &'static str> {
        if v.len() > TINYTEXT_WIDTH {
            return Err("slice too long");
        }

        std::str::from_utf8(v).expect("Must always be UTF8");

        // For reasons I can't say using MaybeUninit::zeroed() is much faster
        // than assigning an array of zeroes (which uses memset instead). Don't remove
        // this without benchmarking (or at least looking at godbolt first).
        // SAFETY: it is safe because u8 is a zeroable type
        let mut t: [u8; TINYTEXT_WIDTH] = unsafe { std::mem::MaybeUninit::zeroed().assume_init() };
        t[..v.len()].copy_from_slice(v);
        Ok(TinyText {
            len_and_collation: LenAndCollation::from_len(v.len() as _),
            t,
        })
    }
