Struct RoleAdminChanged

pub struct RoleAdminChanged {
    pub role: FixedBytes<32>,
    pub previous_admin_role: FixedBytes<32>,
    pub new_admin_role: FixedBytes<32>,
}

Emitted when new_admin_role is set as role’s admin role, replacing previous_admin_role.

DEFAULT_ADMIN_ROLE is the starting admin for all roles, despite RoleAdminChanged not being emitted signaling this. Event with signature RoleAdminChanged(bytes32,bytes32,bytes32) and selector 0xbd79b86ffe0ab8e8776151514217cd7cacd52c909f66475c3af44e129f0b00ff.

event RoleAdminChanged(bytes32 indexed role, bytes32 indexed previous_admin_role, bytes32 indexed new_admin_role);

Fields

role: FixedBytes<32>

previous_admin_role: FixedBytes<32>

new_admin_role: FixedBytes<32>

Trait Implementations

impl Clone for RoleAdminChanged

fn clone(&self) -> RoleAdminChanged

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<&RoleAdminChanged> for LogData

fn from(this: &RoleAdminChanged) -> LogData
