#[non_exhaustive]#[repr(u8)]pub enum Authority {
AuthControlled = 0,
OwnerControlled = 1,
RbacControlled {
role: RoleSymbol,
},
}Expand description
Identifies which authority is allowed to invoke an authority-gated procedure on an account.
Components that gate state-mutating procedures (such as
TokenPolicyManager for set_mint_policy /
set_burn_policy, or the fungible token metadata setters) consult this single shared slot via
the MASM helper authority::assert_authorized. Installing the Authority component on an
account thus selects the gating mode for all such procedures in one place.
§Safety invariant for Authority::AuthControlled
Because assert_authorized is a no-op under AuthControlled, the account’s auth component
is the sole gate for every authority-gated setter. The auth component MUST therefore
authenticate every such setter root, otherwise the setters become permissionless.
Storage layout: [authority, role_symbol_or_zero, 0, 0] — single Word.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
AuthControlled = 0
Authority is the account’s auth component; no extra check is performed by
authority::assert_authorized.
OwnerControlled = 1
Authority is the Ownable2Step owner; the call
must be sent by the registered owner.
RbacControlled
Authority is membership in a specific RBAC role. The call must be sent by an account that
holds role in the
RoleBasedAccessControl component.
Requires the RoleBasedAccessControl
component to be installed on the account; the MASM helper calls into
rbac::assert_sender_has_role and will fail to link otherwise.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example

Enables the styling Attribute value.

attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():

wrap(), which have the same functionality but are

👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().

Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
