Enum NativeScript 

pub enum NativeScript {
    ScriptPubkey(AddrKeyhash),
    ScriptAll(Vec<NativeScript>),
    ScriptAny(Vec<NativeScript>),
    ScriptNOfK(i64, Vec<NativeScript>),
    InvalidBefore(u64),
    InvalidHereafter(u64),
}

A native script tree with stack-safe CBOR, clone, equality and drop operations.

This type implements Drop to dismantle deep trees iteratively. To consume a child list, match by mutable reference and use std::mem::take. This stack-safety guarantee does not cover Serde, debug formatting or downstream tree visitors.

Variants

ScriptPubkey(AddrKeyhash)

ScriptAll(Vec<NativeScript>)

ScriptAny(Vec<NativeScript>)

ScriptNOfK(i64, Vec<NativeScript>)

The ledger CDDL types this threshold signed (int32 in Shelley, widened to int64 in Allegra), not uint; do not narrow it back.

InvalidBefore(u64)

InvalidHereafter(u64)

Trait Implementations

impl Clone for NativeScript

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NativeScript

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

Formats the value using the given formatter.

impl<'b, C> Decode<'b, C> for NativeScript

fn decode(d: &mut Decoder<'b>, ctx: &mut C) -> Result<Self, Error>

Decode a value using the given Decoder.

fn nil() -> Option<Self>

If possible, return a nil value of Self.

impl<'de> Deserialize<'de> for NativeScript

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Drop for NativeScript

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<C> Encode<C> for NativeScript

fn encode<W: Write>( &self, e: &mut Encoder<W>, ctx: &mut C, ) -> Result<(), Error<W::Error>>

Encode a value of this type using the given Encoder.

fn is_nil(&self) -> bool

Is this value of Self a nil value?

impl Eq for NativeScript

impl PartialEq for NativeScript

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for NativeScript

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToCanonicalJson for NativeScript

fn to_json(&self) -> Value

Building the tree is stack-safe, but the returned serde_json::Value is not: serializing, cloning, comparing and dropping it recurse per nesting level, and a chain-deep script overflows a 2 MiB stack doing so. Use to_json_string when the depth is not under your control.

fn to_json_string(&self) -> String

Writes the JSON text directly, never building a serde_json::Value, so no step of rendering a chain-deep script can overflow the stack.

impl TreeNode for NativeScript

fn children(&self) -> &[Self]

fn children_mut(&mut self) -> Option<&mut Vec<Self>>

The child list, or None for leaf variants.
