Struct RoleData

pub struct RoleData {
    pub has_role: StorageMap<Address, StorageBool>,
    pub admin_role: StorageFixedBytes<32>,
}

Information about a specific role.

Fields

has_role: StorageMap<Address, StorageBool>

Whether an account is member of a certain role.

admin_role: StorageFixedBytes<32>

The admin role for this role.

Trait Implementations

impl StorageType for RoleData

const SLOT_BYTES: usize = 32usize

The number of bytes in a slot needed to represent the type. Must not exceed 32. For types larger than 32 bytes that are stored inline with a struct’s fields, set this to 32 and return the full size in StorageType::new.

const REQUIRED_SLOTS: usize = 2usize

The number of words this type must fill. For primitives this is always 0. For complex types requiring more than one inline word, set this to the total size.

type Wraps<'a> = StorageGuard<'a, RoleData> where Self: 'a

For primitive types, this is the type being stored. For collections, this is the StorageType being collected.

type WrapsMut<'a> = StorageGuardMut<'a, RoleData> where Self: 'a

Mutable accessor to the type being stored.

unsafe fn new(root: U256, offset: u8) -> Self

Where in persistent storage the type should live. Although useful for framework designers creating new storage types, most user programs shouldn’t call this. Note: implementations will have to be const once generic_const_exprs stabilizes.

fn load<'s>(self) -> Self::Wraps<'s>

Load the wrapped type, consuming the accessor. Note: most types have a get and/or getter, which don’t consume Self.

fn load_mut<'s>(self) -> Self::WrapsMut<'s>

Load the wrapped mutable type, consuming the accessor. Note: most types have a set and/or setter, which don’t consume Self.
