Struct LimitedString

Source

pub struct LimitedString(/* private fields */);

Expand description

A wrapper type for a String which limits the length of the string to u8::MAX.

Implementations§

Source §

impl LimitedString

Source

pub fn new(s: String) -> Result<Self, InvalidLengthError>

Create a new LimitedString from a String.

Returns None if the String is too long.

Source

pub fn len(&self) -> u8

Return the length of the string.

Is returned as an u8 as it is guaranteed to be <= u8::MAX.

Source

pub fn as_str(&self) -> &str

Get a reference to the string.

Source

pub fn as_bytes(&self) -> &[u8] ⓘ

Get a reference to the byte representation of the string.
