Struct StorageInfo 

pub struct StorageInfo<'info, TypeId: Clone> {
    pub keys: Cow<'info, [StorageKeyInfo<TypeId>]>,
    pub value_id: TypeId,
    pub default_value: Option<Cow<'info, [u8]>>,
}

Information about a storage entry.

Fields

keys: Cow<'info, [StorageKeyInfo<TypeId>]>

No entries if a plain storage entry, or N entries for N maps.

value_id: TypeId

The type of the values.

default_value: Option<Cow<'info, [u8]>>

Bytes representing the default value for this entry, if one exists.

Implementations

impl<'info, TypeId: Clone + 'static> StorageInfo<'info, TypeId>

pub fn into_owned(self) -> StorageInfo<'static, TypeId>

Take ownership of this StorageInfo, turning any lifetimes to 'static.

pub fn map_ids<NewTypeId: Clone, E, F: FnMut(TypeId) -> Result<NewTypeId, E>>( self, f: F, ) -> Result<StorageInfo<'static, NewTypeId>, E>

Map the type IDs in this StorageInfo, returning a new one or bailing early with an error if something goes wrong. This also takes ownership of the StorageInfo, turning the lifetime to static.

Trait Implementations

impl<'info, TypeId: Clone + Clone> Clone for StorageInfo<'info, TypeId>

fn clone(&self) -> StorageInfo<'info, TypeId>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'info, TypeId: Debug + Clone> Debug for StorageInfo<'info, TypeId>

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

Formats the value using the given formatter.

impl<'info, TypeId: PartialEq + Clone> PartialEq for StorageInfo<'info, TypeId>

fn eq(&self, other: &StorageInfo<'info, TypeId>) -> 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.
