Struct Storage

pub struct Storage { /* private fields */ }

An ink! storage struct definition.

Noticed by ink! through the #[ink(storage)] annotation.

Note

An ink! smart contract must have exactly one storage definition. The storage definition must be found in the root of the ink! module.

Example

#[ink(storage)]
pub struct MyStorage {
    my_value: bool,
    counter: u32,
}

Implementations

impl Storage

pub fn attrs(&self) -> &[Attribute]

Returns the non-ink! attributes of the ink! storage struct.

pub fn ident(&self) -> &Ident

Returns the identifier of the storage struct.

pub fn generics(&self) -> &Generics

Returns the generics of the storage struct.

pub fn fields(&self) -> Iter<'_, Field>

Returns an iterator yielding all fields of the storage struct.

Trait Implementations

impl Debug for Storage

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

Formats the value using the given formatter.

impl From<Storage> for InkItem

fn from(storage: Storage) -> Self

Converts to this type from the input type.

impl PartialEq for Storage

fn eq(&self, other: &Storage) -> 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 ToTokens for Storage

fn to_tokens(&self, tokens: &mut TokenStream)

We mainly implement this trait for this ink! type to have a derived Spanned implementation for it.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.

impl TryFrom<ItemStruct> for Storage

type Error = Error

The type returned in the event of a conversion error.

fn try_from(item_struct: ItemStruct) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Storage
