Enum 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 for ManagedString<'a, T>

where T: Clone + ArrayLength<u8>,

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T> Debug for ManagedString<'a, T>

where T: Debug + ArrayLength<u8>,

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

Formats the value using the given formatter.

impl<'a, 'de, T> Deserialize<'de> for ManagedString<'a, T>

where 'de: 'a, T: ArrayLength<u8>,

fn deserialize<D>( deserializer: D, ) -> Result<ManagedString<'a, T>, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

We can deserialize as a borrowed str

impl<'a, T> PartialEq for ManagedString<'a, T>

where T: PartialEq + ArrayLength<u8>,

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, T> Serialize for ManagedString<'a, T>

where T: ArrayLength<u8>,

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

where S: Serializer,

We can serialize our managed string as a str

impl<'a, T> Eq for ManagedString<'a, T>

where T: Eq + ArrayLength<u8>,

impl<'a, T> StructuralPartialEq for ManagedString<'a, T>

where T: ArrayLength<u8>,
