    ScriptKeyUnknown = 0,
    ScriptKeyBip86 = 1,
    ScriptKeyScriptPathExternal = 2,

}

Variants

ScriptKeyUnknown = 0

The type of script key is not known. This should only be stored for assets where we don’t know the internal key of the script key (e.g. for imported proofs).

ScriptKeyBip86 = 1

The script key is a normal BIP-86 key. This means that the internal key is turned into a Taproot output key by applying a BIP-86 tweak to it.

ScriptKeyScriptPathExternal = 2

The script key is a key that contains a script path that is defined by the user and is therefore external to the tapd wallet. Spending this key requires providing a specific witness and must be signed through the vPSBT signing flow.

ScriptKeyBurn = 3

The script key is a specific un-spendable key that indicates a burnt asset. Assets with this key type can never be spent again, as a burn key is a tweaked NUMS key that nobody knows the private key for.

ScriptKeyTombstone = 4

The script key is a specific un-spendable key that indicates a tombstone output. This is only the case for zero-value assets that result from a non-interactive (TAP address) send where no change was left over.

ScriptKeyChannel = 5

The script key is used for an asset that resides within a Taproot Asset Channel. That means the script key is either a funding key (OP_TRUE), a commitment output key (to_local, to_remote, htlc), or a HTLC second-level transaction output key. Keys related to channels are not shown in asset balances (unless specifically requested) and are never used for coin selection.

ScriptKeyUniquePedersen = 6

The script key is derived using the asset ID and a single leaf that contains an un-spendable Pedersen commitment key (OP_CHECKSIG <NUMS_key + asset_id * G>). This can be used to create unique script keys for each virtual packet in the fragment, to avoid proof collisions in the universe, where the script keys should be spendable by a hardware wallet that only supports miniscript policies for signing P2TR outputs.

Implementations

impl ScriptKeyType

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of ScriptKeyType.

pub fn from_i32(value: i32) -> Option<ScriptKeyType>

👎Deprecated:

Use the TryFrom<i32> implementation instead

Converts an i32 to a ScriptKeyType, or None if value is not a valid variant.

impl ScriptKeyType

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for ScriptKeyType

fn clone(&self) -> ScriptKeyType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScriptKeyType

impl Debug for ScriptKeyType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ScriptKeyType

fn default() -> ScriptKeyType

Returns the “default value” for a type.

impl Eq for ScriptKeyType

impl From<ScriptKeyType> for i32

fn from(value: ScriptKeyType) -> i32

Converts to this type from the input type.

impl Hash for ScriptKeyType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ScriptKeyType

fn cmp(&self, other: &ScriptKeyType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ScriptKeyType

fn eq(&self, other: &ScriptKeyType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ScriptKeyType

fn partial_cmp(&self, other: &ScriptKeyType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralPartialEq for ScriptKeyType

impl TryFrom<i32> for ScriptKeyType

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<ScriptKeyType, UnknownEnumValue>

Performs the conversion.
