Enum anachro_icd::ManagedString

pub enum ManagedString<'a, T> where
    T: ArrayLength<u8>,  {
    Owned(String<T>),
    Borrow(&'a str),
}

A borrowed or owned string

Basically like CoW, but with heapless::String

Variants

Owned(String<T>)

Borrow(&'a str)

Implementations

impl<'a, T> ManagedString<'a, T> where
    T: ArrayLength<u8>, 

pub fn as_str(&self) -> &str

Obtain self as a string slice

pub fn as_borrowed(&'a self) -> ManagedString<'a, T>

Retrieve a borrowed copy of the string

pub fn try_from_str(input: &str) -> Result<ManagedString<'static, T>, ()>

Attempt to create an Owned string from a given str

May fail if the heapless::String is not large enough to contain this slice

pub fn borrow_from_str(input: &str) -> ManagedString<'_, T>

Create a Borrowed string from a given str

pub fn try_to_owned(&self) -> Result<ManagedString<'static, T>, ()>

Attempt to convert to an Owned string from the current state

May fail if the heapless::String is not large enough to contain this slice

Trait Implementations

impl<'a, T: Clone> Clone for ManagedString<'a, T> where
    T: ArrayLength<u8>, 

fn clone(&self) -> ManagedString<'a, T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for ManagedString<'a, T> where
    T: ArrayLength<u8>, 

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, 'de: 'a, T> Deserialize<'de> for ManagedString<'a, T> where
    T: ArrayLength<u8> + Sized, 

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'de>,

    T: ArrayLength<u8>, 

impl<'a, T: PartialEq> PartialEq<ManagedString<'a, T>> for ManagedString<'a, T> where
    T: ArrayLength<u8>, 

fn eq(&self, other: &ManagedString<'a, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ManagedString<'a, T>) -> bool

This method tests for !=.

    T: ArrayLength<u8>, 

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

We can serialize our managed string as a str
