Enum MapRepresentation

pub enum MapRepresentation {
    List(Vec<MapEntry>),
    Template(StoragePlaceholder),
}

Supported map representations for a component’s storage entries.

Variants

List(Vec<MapEntry>)

Template(StoragePlaceholder)

Implementations

impl MapRepresentation

pub fn all_placeholders_iter( &self, ) -> Box<dyn Iterator<Item = (&StoragePlaceholder, PlaceholderType)> + '_>

Returns an iterator over all of the storage entries’s placeholder keys, alongside their expected type.

pub fn len(&self) -> Option<usize>

Returns the amount of key-value pairs in the entry, or None if the representation is a placeholder.

pub fn is_empty(&self) -> bool

Returns true if the map is represented by a list of key-value entries, and the list is empty. Returns false otherwise

pub fn try_build_map( &self, init_storage_data: &InitStorageData, ) -> Result<StorageMap, AccountComponentTemplateError>

Attempts to convert the MapRepresentation into a StorageMap.

If the representation is a template, the value is retrieved from init_storage_data, identified by its key. If any of the inner elements within the value are a template, they are retrieved in the same way.

Trait Implementations

impl Clone for MapRepresentation

fn clone(&self) -> MapRepresentation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MapRepresentation

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

Formats the value using the given formatter.

impl Deserializable for MapRepresentation

fn read_from<R>( source: &mut R, ) -> Result<MapRepresentation, DeserializationError>

where R: ByteReader,

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

impl PartialEq for MapRepresentation

fn eq(&self, other: &MapRepresentation) -> 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 Serializable for MapRepresentation

fn write_into<W>(&self, target: &mut W)

where W: ByteWriter,

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
