Trait Implementations

impl Clone for Legacy

fn clone(&self) -> Legacy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Legacy

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

Formats the value using the given formatter.

impl Eq for Legacy

impl Ord for Legacy

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

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Legacy> for Legacy

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Legacy> for Legacy

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

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

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

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

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

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

impl ScriptContext for Legacy

fn check_frag_non_malleable<Pk, Ctx>(
    frag: &Terminal<Pk, Ctx>
) -> Result<(), ScriptContextError> where
    Ctx: ScriptContext,
    Pk: MiniscriptKey, 

Depending on ScriptContext, fragments can be malleable. For Example, under Legacy context, PkH is malleable because it is possible to estimate the cost of satisfaction because of compressed keys This is currently only used in compiler code for removing malleable compilations. This does NOT recursively check if the children of the fragment are valid or not. Since the compilation proceeds in a leaf to root fashion, a recursive check is unnecessary.

fn check_frag_validity<Pk, Ctx>(
    _frag: &Terminal<Pk, Ctx>
) -> Result<(), ScriptContextError> where
    Ctx: ScriptContext,
    Pk: MiniscriptKey, 

Depending on script Context, some of the Terminals might not be valid. For example, in Segwit Context with MiniscriptKey as bitcoin::PublicKey uncompressed public keys are non-standard and thus invalid. Post Tapscript upgrade, this would have to consider other nodes. This does not recursively check
