pub struct BurnPolicy { /* private fields */ }Expand description
Descriptor for the burn policy registered with a super::TokenPolicyManager.
Binds the procedure root the manager dispatches to (via dynexec) with any companion
AccountComponents that must be installed for the procedure to work.
Construct via Self::allow_all, Self::owner_only, Self::min_burn_amount, or
Self::custom. Pass to the super::TokenPolicyManager builder via active_burn_policy
or allowed_burn_policy.
Implementations§
Source§impl BurnPolicy
impl BurnPolicy
Sourcepub fn allow_all() -> BurnPolicy
pub fn allow_all() -> BurnPolicy
Returns a burn policy that accepts every burn unconditionally.
Sourcepub fn owner_only() -> BurnPolicy
pub fn owner_only() -> BurnPolicy
Returns a burn policy gated by the account owner.
Sourcepub fn min_burn_amount(min_burn_amount: AssetAmount) -> BurnPolicy
pub fn min_burn_amount(min_burn_amount: AssetAmount) -> BurnPolicy
Returns a burn policy that rejects burns below min_burn_amount.
The threshold is written to the MinBurnAmount component’s storage slot and can be
updated at runtime through the owner-gated set_min_burn_amount procedure.
Sourcepub fn custom<I>(
root: AccountProcedureRoot,
components: I,
) -> Result<BurnPolicy, BurnPolicyError>
pub fn custom<I>( root: AccountProcedureRoot, components: I, ) -> Result<BurnPolicy, BurnPolicyError>
Returns a burn policy resolving to root and shipping the provided companion
components (anything that can be converted into an AccountComponent).
§Errors
Returns BurnPolicyError::RootNotInComponents if root is not the procedure root of
any procedure exported by the provided components.
Sourcepub fn root(&self) -> AccountProcedureRoot
pub fn root(&self) -> AccountProcedureRoot
Returns the procedure root of the policy this descriptor resolves to.

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().

Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().

Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
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);
