pub const NULLFAIL: Self

Require failed signature checks to consume empty signatures.

pub const WITNESS_PUBKEYTYPE: Self

Require compressed public keys in segwit scripts.

pub const CONST_SCRIPTCODE: Self

Discourage unknown public-key versions in tapscript.

pub const MANDATORY: Self

Mandatory consensus flags used for block validation after taproot activation.

pub const STANDARD: Self

Standard relay flags; useful for vector tests that request policy checks.

pub const fn from_bits(bits: u32) -> Self

Builds flags from raw Core-compatible bits.

pub const fn bits(self) -> u32

Returns raw Core-compatible flag bits.

pub const fn consensus_bits(self) -> u32

Returns only the bits accepted by rust-bitcoin’s bitcoinconsensus backend.

pub const fn kernel_bits(self) -> u32

Returns the full consensus-authority bit set, including taproot for bitcoinkernel.

pub const fn contains(self, other: Self) -> bool

Returns true when all other bits are present.

pub const fn union(self, other: Self) -> Self

Adds another flag set.

pub fn from_core_names(names: &str) -> Result<Self, ScriptError>

Parses a comma-separated Core test-vector flag string.

Trait Implementations

impl Clone for VerifyFlags

fn clone(&self) -> VerifyFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VerifyFlags

impl Debug for VerifyFlags

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

Formats the value using the given formatter.

impl Default for VerifyFlags

fn default() -> VerifyFlags

Returns the “default value” for a type.

impl Eq for VerifyFlags

impl From<VerifyFlags> for u32

fn from(flags: VerifyFlags) -> Self

Converts to this type from the input type.

impl Hash for VerifyFlags

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 PartialEq for VerifyFlags

fn eq(&self, other: &VerifyFlags) -> 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.
