Struct ergo_lib_wasm::ergo_tree::ErgoTree

pub struct ErgoTree(_);

The root of ErgoScript IR. Serialized instances of this class are self sufficient and can be passed around.

Implementations

impl ErgoTree

pub fn from_base16_bytes(s: &str) -> Result<ErgoTree, JsValue>

Decode from base16 encoded serialized ErgoTree

pub fn from_bytes(data: Vec<u8>) -> Result<ErgoTree, JsValue>

Decode from encoded serialized ErgoTree

pub fn to_bytes(&self) -> Vec<u8>

Encode Ergo tree as serialized bytes

pub fn to_base16_bytes(&self) -> String

Returns Base16-encoded serialized bytes

pub fn constants_len(&self) -> Result<usize, JsValue>

Returns constants number as stored in serialized ErgoTree or error if the parsing of constants is failed

pub fn get_constant(&self, index: usize) -> Result<Option<Constant>, JsValue>

Returns constant with given index (as stored in serialized ErgoTree) or None if index is out of bounds or error if constants parsing were failed

pub fn set_constant(
    &mut self,
    index: usize,
    constant: &Constant
) -> Result<Option<Constant>, JsValue>

Sets new constant value for a given index in constants list (as stored in serialized ErgoTree), and returns previous constant or None if index is out of bounds or error if constants parsing were failed

pub fn template_bytes(&self) -> Result<Vec<u8>, JsValue>

Serialized proposition expression of SigmaProp type with ConstantPlaceholder nodes instead of Constant nodes

Trait Implementations

impl Clone for ErgoTree

fn clone(&self) -> ErgoTree

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErgoTree

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

Formats the value using the given formatter.

impl From<ErgoTree> for ErgoTree

fn from(original: ErgoTree) -> ErgoTree

Performs the conversion.

impl FromWasmAbi for ErgoTree

type Abi = u32

The wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for ErgoTree

type Abi = u32

The wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for ErgoTree

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for ErgoTree

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl PartialEq<ErgoTree> for ErgoTree

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

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

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

This method tests for !=.

impl RefFromWasmAbi for ErgoTree

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, ErgoTree>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for ErgoTree

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, ErgoTree>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi
