Struct InitStorageData

pub struct InitStorageData { /* private fields */ }

Represents the data required to initialize storage entries when instantiating an AccountComponent from a template.

An InitStorageData can be created from a TOML string when the std feature flag is set.

Implementations

impl InitStorageData

pub fn new( entries: impl IntoIterator<Item = (StorageValueName, String)>, ) -> Self

Creates a new instance of InitStorageData.

A BTreeMap is constructed from the passed iterator, so duplicate keys will cause overridden values.

Parameters

• entries: An iterable collection of key-value pairs.

pub fn placeholders(&self) -> &BTreeMap<StorageValueName, String>

Retrieves a reference to the storage placeholders.

pub fn get(&self, key: &StorageValueName) -> Option<&String>

Returns a reference to the name corresponding to the placeholder, or Option::None if the placeholder is not present.

impl InitStorageData

pub fn from_toml(toml_str: &str) -> Result<Self, InitStorageDataError>

Creates an instance of InitStorageData from a TOML string.

This method parses the provided TOML and flattens nested tables into dot‑separated keys using StorageValueName as keys. All values are converted to plain strings (so that, for example, key = 10 and key = "10" both yield String::from("10") as the value).

Errors

• If duplicate keys or empty tables are found in the string
• If the TOML string includes arrays
