Struct Interpreter

pub struct Interpreter {
    pub cursor: Cursor,
    actions: Vec<InterpreterAction>,
    handler: Handler,
    pub node_builder: NodeBuilder,
    breakpoints: Vec<Breakpoint>,
    pub watchpoints: Vec<Watchpoint>,
    saved_cursors: Vec<Cursor>,
    filename_to_program: HashMap<PathBuf, String>,
    parsed_inputs: u32,
    network: NetworkName,
}

Contains the state of interpretation, in the form of the Cursor, as well as information needed to interact with the user, like the breakpoints.

Fields

cursor: Cursor

actions: Vec<InterpreterAction>

handler: Handler

node_builder: NodeBuilder

breakpoints: Vec<Breakpoint>

watchpoints: Vec<Watchpoint>

saved_cursors: Vec<Cursor>

filename_to_program: HashMap<PathBuf, String>

parsed_inputs: u32

network: NetworkName

The network.

Implementations

impl Interpreter

pub fn new<'a, Q: 'a + AsRef<Path> + ?Sized>( leo_source_files: &[(PathBuf, Vec<PathBuf>)], aleo_source_files: impl IntoIterator<Item = &'a Q>, signer: Value, block_height: u32, network: NetworkName, ) -> Result<Self>

fn get_ast( path: &PathBuf, modules: &[PathBuf], handler: &Handler, node_builder: &NodeBuilder, network: NetworkName, ) -> Result<Ast>

Parses a Leo source file and its modules into an Ast.

Arguments

• path: The path to the main .leo source file (e.g. main.leo).
• modules: A list of paths to module .leo files associated with the main file.
• handler: The compiler’s diagnostic handler for reporting errors.
• node_builder: Utility for constructing unique node IDs in the AST.
• network: The target network.

Returns

• Ok(Ast): If parsing succeeds.
• Err(CompilerError): If file I/O or parsing fails.

Behavior

• Reads the contents of the main file and all modules.
• Registers each source file with the compiler’s source map (via with_session_globals).
• Invokes the parser to produce the full AST including modules.

fn new_impl( leo_source_files: &[(PathBuf, Vec<PathBuf>)], aleo_source_files: &mut dyn Iterator<Item = &Path>, signer: Value, block_height: u32, network: NetworkName, ) -> Result<Self>

pub fn save_cursor(&mut self)

pub fn restore_cursor(&mut self) -> bool

Returns false if there was no saved cursor to restore.

fn get_aleo_program(path: &Path) -> Result<Program<TestnetV0>>

pub fn update_watchpoints(&mut self) -> Result<bool>

Returns true if any watchpoints changed.

pub fn action(&mut self, act: InterpreterAction) -> Result<Option<Value>>

pub fn view_current(&self) -> Option<impl Display>

pub fn view_current_in_context(&self) -> Option<(impl Display, usize, usize)>
