Struct Runtime 

pub struct Runtime { /* private fields */ }

Implementations

impl Runtime

pub fn new(state: RuntimeState) -> Self

pub fn is_empty(&self) -> bool

pub fn clear(&mut self)

pub fn resolve( &mut self, target: &mut dyn Target, program: &Program, timezone: &TimeZone, ) -> RuntimeResult

Resolves the provided Program to completion using the given Target.

This function ensures that the target contains a valid root object before proceeding. If the target is invalid or missing, an error is returned. The resolution process is performed using a Context that maintains execution state and timezone information.

Arguments

• target - A mutable reference to an object implementing the Target trait. This serves as the execution environment for resolving the program.
• program - A reference to the Program that needs to be resolved.
• timezone - A reference to the TimeZone used for resolving time-dependent expressions.

Returns

Returns a RuntimeResult, which is either:

• Ok(value): The program resolved successfully, producing a value.
• Err(Terminate::Error): A fatal error occurred during resolution.
• Err(Terminate::Abort): The resolution was aborted due to a non-fatal expression error.

Errors

The function may return an error in the following cases:

• If the target does not contain a valid root object, an error is returned.
• If the resolution process encounters an ExpressionError::Error.
• If the program execution results in an ExpressionError::Abort, ExpressionError::Fallible, or ExpressionError::Missing, the function aborts with Terminate::Abort.
