Struct pact::Unspecified

pub struct Unspecified {}

Placeholder struct for “unspecified” pact data.

Every pact has an Unspecified data type with ordinal 0. Data of this type is used as the default data in every pact.

The exact contents of this data are entirely unspecified; they could be “null” or empty (the most common case), or could contain an undocumented sequence of data. That’s why we call this type Unspecified instead of something like Null or Void.

Trait Implementations

impl Clone for Unspecified

fn clone(&self) -> Unspecified

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Unspecified

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

Formats the value using the given formatter.

impl Decodable for Unspecified

fn decode( &mut self, _reader: &mut (impl ReadsDecodable + ?Sized), _header: Option<DataHeader> ) -> Result<(), CodecError>

Decodes data with format from reader into this thing count times.

fn decode_from( reader: &mut (impl ReadsDecodable + ?Sized) ) -> Result<Self, CodecError>

where Self: Default,

Returns a new, default Self decoded from reader.

impl Default for Unspecified

fn default() -> Unspecified

Returns the “default value” for a type.

impl Encodable for Unspecified

const FORMAT: Format = Format::Fluid

This thing’s Format.

fn encode( &self, _writer: &mut (impl WritesEncodable + ?Sized) ) -> Result<(), CodecError>

Encodes this thing’s data into writer.

fn encode_header( &self, writer: &mut (impl WritesEncodable + ?Sized) ) -> Result<(), CodecError>

Encodes the header for this thing’s data format into writer.

impl PartialEq for Unspecified

fn eq(&self, other: &Unspecified) -> bool

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

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

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