Struct StorageBackedBytes 

pub struct StorageBackedBytes {
    pub base_key: B256,
    pub account: Address,
}

Variable-length byte storage.

Layout: offset 0 holds the byte length; offsets 1..N hold 32-byte chunks with the trailing partial chunk right-aligned in its slot.

Fields

base_key: B256

account: Address
