Struct fixed_len_str_example::FixedStr12

#[repr(transparent)]
pub struct FixedStr12 {
    pub array: [u8; 12],
}

A fixed length string with a length of 12.

Fields

array: [u8; 12]

Methods

impl FixedStr12

pub const fn new(array: [u8; 12]) -> Self

Creates an FixedStr12 from an array,in the future this will be unsafe because it does not checks if the bytes are valid utf8.

pub fn as_bytes(&self) -> &[u8]

Borrow the internal array as an slice.

pub unsafe fn as_bytes_mut(&mut self) -> &mut [u8]

Borrow the internal array as a mutable slice.

Safety

This is unsafe due to allow modifications that can produce invalid utf8.

pub fn fill_zeroes_char(&mut self, character: char)

Fill the last spaces in zero of the buffer with a determinated character.Useful when constructing the array with all bytes in zero and then filling them in an incremental way.

Panics

This will panic on debug if the zero spaces are not sufficient for the non-zero spaces of the character interpreted as \[u8; 4\].

pub fn fill_zeroes_str(&mut self, s: &str)

Fill the last spaces in zero of the buffer with a determinated string.Useful when constructing the array with all bytes in zero and then filling them in an incremental way.

Panics

This will panic on debug if the zero spaces are not sufficient for the non-zero spaces of the string interpreted as &\[u8\].

pub fn into_vec(self) -> Vec<u8>

Convert the FixedStr12 into a vector of bytes.

pub fn into_string(self) -> String

Turn the FixedStr12 into a string,moving the bytes.

pub fn from_vec(vec: Vec<u8>) -> FixedStr12

Construct a FixedStr12 from a vector of bytes,truncating or pushing zeroes to adjust the size to 12.

Using this function with multi-byte characters can easely produce an unexpected value.

pub fn from_string(string: String) -> FixedStr12

Construct a FixedStr12 from a String,truncating or pushing zeroes to adjust the size to 12.

Using this function with multi-byte characters can easely produce an unexpected value.
