RuntimeError

Struct RuntimeError 

Source
pub struct RuntimeError {
    pub instr: Instr,
    pub code: SmolStr,
    pub message: SmolStr,
}
Expand description

A run-time error no try caught, as the VM hands it back to whoever ran the program.

It records the instruction that failed, the error’s name and its message. Pair it with the program’s ErrorCtx to place it in the source: turn it into a Diagnostic with Self::diagnostic, or print the report and end the program with Self::report.

Fields§

§instr: Instr§code: SmolStr

The error’s name, such as index_out_of_bounds, or the name a throw gave it.

§message: SmolStr

The message, with the terminal colors the printed report shows.

Implementations§

Source§

impl RuntimeError

Source

pub fn new(instr: Instr, t: ErrType<'_>) -> Self

Source

pub fn diagnostic(&self, ctx: &ErrorCtx<'_>) -> Diagnostic

The error as a Diagnostic, its message without terminal colors.

Source

pub fn report(&self, ctx: &ErrorCtx<'_>) -> !

Reports the error the way a program that stops on it does: prints the report to stderr and ends the process, or, inside collect_diagnostic, hands the error to it as a Diagnostic.

fn fg(&self, value: Color) -> Painted<&T>

use yansi::{Paint, Color};

painted.fg(Color::White);

Set foreground color to white using white().

§

fn quirk(&self, value: Quirk) -> Painted<&T>

Returns self with the quirk() set to [Quirk :: Clear].

§Example
