Struct DynamicDataValue

pub struct DynamicDataValue { /* private fields */ }

Contents of a Dynamic::Data.

Implementations

impl DynamicDataValue

pub fn new(typing: &DataType) -> Self

Returns a new, default data value of typing.

pub fn reset(&mut self)

Removes all values from this data, resetting them to their default values.

pub fn insert(&mut self, name: Text, value: Dynamic)

Inserts a value for the field with name.

pub fn iter(&self) -> impl Iterator<Item = (&DataField, Option<&Dynamic>)>

Returns an iterator over all fields in the data.

The iterator yields fields in order by ordinal, yielding None for unset fields.

pub fn visit_mut(&mut self, proc: impl FnMut(&DataField, &mut Dynamic))

Applies proc to each field in the data.

Fields are visited in order by ordinal. If a field is unset, it will be initialized to a default value before proc is invoked.

Trait Implementations

impl Clone for DynamicDataValue

fn clone(&self) -> DynamicDataValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DynamicDataValue

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

Formats the value using the given formatter.

impl Decodable for DynamicDataValue

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

Decodes data with header from reader into this thing.

fn ensure_header( header: Option<DataHeader>, supported_ordinals: &[FormatMetadata], ) -> Result<DataHeader, CodecError>

Returns Ok(header) iff header exists and matches one of suppported_ordinals.

fn ensure_no_header(header: Option<DataHeader>) -> Result<(), CodecError>

Returns Ok(()) iff header is None.

impl Encodable for DynamicDataValue

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 without encoding a DataHeader.

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

Encodes this thing’s data header into writer.

impl PartialEq for DynamicDataValue

fn eq(&self, other: &DynamicDataValue) -> 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.
