Struct NilString 

pub struct NilString<T>(pub Option<T>);

Optional field, which encodes None as empty string (0x80).

T must never be encodable to 0x80 since it will resolve to None.

Tuple Fields

0: Option<T>

Trait Implementations

impl<T: Clone> Clone for NilString<T>

fn clone(&self) -> NilString<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for NilString<T>

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

Formats the value using the given formatter.

impl<T: Decodable> Decodable for NilString<T>

fn decode(buf: &mut &[u8]) -> Result<Self>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.

impl<T: Default> Default for NilString<T>

fn default() -> NilString<T>

Returns the “default value” for a type.

impl<T: Encodable> Encodable for NilString<T>

fn encode(&self, out: &mut dyn BufMut)

Encodes the type into the out buffer.

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

impl<T: PartialEq> PartialEq for NilString<T>

fn eq(&self, other: &NilString<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.
