Enum ScriptError 

pub enum ScriptError {
    Parse {
        line: usize,
        message: String,
    },
    UnknownKeyword {
        line: usize,
        keyword: String,
        context: &'static str,
    },
    MissingOutput,
    NoStructures,
    UnclosedBlock(&'static str),
    Io {
        path: PathBuf,
        message: String,
    },
    Pack(PackError),
}

Errors produced by the script module — from parsing, file loading, or the downstream pack() call invoked by a script-driven run.

Variants

Parse

Parse error with line number and diagnostic message.

Fields

line: usize

message: String

UnknownKeyword

An unrecognised keyword appeared where a known one was expected. Unlike a generic parse error, this carries the offending token and the context block so error messages can suggest fixes.

Fields

line: usize

keyword: String

context: &'static str

MissingOutput

Script is missing a required output keyword.

NoStructures

Script contains zero structure blocks.

UnclosedBlock(&'static str)

A structure or atoms block was not closed with end ….

Io

Reading or writing a molecular frame failed.

Fields

path: PathBuf

message: String

Pack(PackError)

The packer itself returned an error.

Trait Implementations

impl Debug for ScriptError

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

Formats the value using the given formatter.

impl Display for ScriptError

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

Formats the value using the given formatter.

impl Error for ScriptError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<PackError> for ScriptError

fn from(err: PackError) -> Self

Converts to this type from the input type.
