Struct ContractArtifact 

pub struct ContractArtifact {
    pub name: String,
    pub functions: Vec<FunctionArtifact>,
    pub outputs: Option<Value>,
    pub file_map: Option<Value>,
    pub context_inputs_sizes: Option<HashMap<String, usize>>,
}

A deserialized contract artifact containing function metadata.

Fields

name: String

Contract name.

functions: Vec<FunctionArtifact>

Functions defined in the contract.

outputs: Option<Value>

Compiler output metadata (opaque JSON).

file_map: Option<Value>

Source file map (opaque JSON).

context_inputs_sizes: Option<HashMap<String, usize>>

Size of the PrivateContextInputs parameter for each private function. Computed during nargo parsing and persisted with the artifact so PXE can reconstruct private-function witnesses after store roundtrips.

Implementations

impl ContractArtifact

pub fn from_json(json: &str) -> Result<Self, Error>

Deserialize a contract artifact from a JSON string.

pub fn find_function(&self, name: &str) -> Result<&FunctionArtifact, Error>

Find a function by name, returning an error if not found.

pub fn find_function_by_type( &self, name: &str, function_type: &FunctionType, ) -> Result<&FunctionArtifact, Error>

Find a function by name and type, returning an error if not found.

pub fn to_buffer(&self) -> Result<Vec<u8>, Error>

Serialize this artifact to a JSON byte buffer.

pub fn from_buffer(buffer: &[u8]) -> Result<Self, Error>

Deserialize an artifact from a JSON byte buffer.

pub fn to_json(&self) -> Result<String, Error>

Serialize to a pretty-printed JSON string.

pub fn from_nargo_json(json: &str) -> Result<Self, Error>

Parse a contract artifact from raw nargo compiler output.

The nargo compiler output has a different structure than the Aztec-processed format. This method handles the conversion:

• Strips __aztec_nr_internals__ prefix from function names
• Maps custom_attributes to function_type (Private/Public/Utility)
• Extracts parameters from abi.parameters
• Computes function selectors from name + parameters
• Filters out the inputs parameter (PrivateContextInputs) from private functions

pub fn find_function_by_selector( &self, selector: &FunctionSelector, ) -> Option<&FunctionArtifact>

Find a function by selector.

pub fn private_context_inputs_size(&self, function_name: &str) -> usize

Count the number of field elements the PrivateContextInputs parameter occupies for a given function. Returns 0 if the function has no such parameter (public/utility functions).

This is needed because compiled Noir bytecode expects the full PrivateContextInputs flattened into the initial witness before user args.

pub fn count_abi_type_fields(typ: &AbiType) -> usize

Count the number of scalar fields an ABI type flattens to.

Trait Implementations

impl Clone for ContractArtifact

fn clone(&self) -> ContractArtifact

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractArtifact

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContractArtifact

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ContractArtifact

fn eq(&self, other: &ContractArtifact) -> 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 Serialize for ContractArtifact

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
