Struct concordium_std::OccupiedEntryRaw

#[repr(transparent)]
pub struct OccupiedEntryRaw<StateApi: HasStateApi> { /* private fields */ }

A view into an occupied entry in a HasStateApi type. It is part of the EntryRaw enum.

Differs from OccupiedEntry in that this has access to the raw bytes stored in the state via a HasStateEntry type.

Implementations

impl<StateApi: HasStateApi> OccupiedEntryRaw<StateApi>

pub fn key(&self) -> &[u8]

Gets a reference to the key that would be used when inserting a value through the OccupiedEntryRaw.

pub fn get_ref(&self) -> &StateApi::EntryType

Gets a reference to the HasStateEntry type in the entry.

pub fn get(self) -> StateApi::EntryType

Converts the entry into its HasStateEntry type.

If you need multiple mutable references to the OccupiedEntryRaw, see get_mut.

pub fn get_mut(&mut self) -> &mut StateApi::EntryType

Gets a mutable reference to the HasStateEntry type in the entry.

If you need access to a HasStateEntry, which can outlive the OccupiedEntryRaw, see get.

pub fn insert_raw(&mut self, value: &[u8])

Sets the value of the entry with the OccupiedEntryRaw’s key.

pub fn insert<V: Serial>(&mut self, value: &V)

Sets the value of the entry with the OccupiedEntryRaw’s key. This differs from insert_raw in that it automatically serializes the value. The insert should be preferred if the value is already a byte array.
