Struct Program 

pub struct Program { /* private fields */ }

This structure is guaranteed to contain valid bytecode and debug info because it may only be constructed from source.

Implementations

impl Program

pub fn eval<'host>(&self) -> Result<Value<'host>, Error>

Errors

Returns an error if the evaluating the program’s root block results in an error

pub fn debug_info(&self) -> &[u8]

pub fn locate_runtime_error(&self, e: &Error) -> Option<(usize, usize)>

pub fn from_str_with_diagnostics<'source>( s: &'source str, for_each: impl FnMut(Diagnostic), ) -> Result<Self, CompilerError<'source>>

Compiles an espy program after iterating through all diagnostics.

Errors

Returns an error if any error diagnostics were found in the ast. Displaying this error is probably uneccessary if error diagnostics were already shown to the user.

Trait Implementations

impl Debug for Program

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

Formats the value using the given formatter.

impl<'source> TryFrom<&'source str> for Program

type Error = CompilerError<'source>

The type returned in the event of a conversion error.

fn try_from(s: &'source str) -> Result<Self, Self::Error>

Performs the conversion.
