Enum ResolveError 

pub enum ResolveError {
    PathTraversal {
        name: String,
    },
    AssetParse {
        source: Box<dyn Error + Send + Sync>,
    },
    Io {
        path: PathBuf,
        source: Error,
    },
}

Error type for module resolution.

Structurally represents domain-specific errors that occur during resolve(). Converted to a Lua error via mlua::Error::external() and can be recovered on the caller side with err.downcast_ref::<ResolveError>().

Construction-time errors (e.g. root directory not found) are returned as sandbox::InitError and are not included here.

Variants

PathTraversal

Path access outside the sandbox detected.

Raised both by genuine escape attempts and by a legitimate symlink whose target lies outside the root. For the latter, build the resolver with resolvers::FsResolver::new_symlink_aware so the symlink targets become part of the allowed set.

Fields

name: String

AssetParse

Asset parse failure.

Generalized to hold different error types per parser. resolvers::json_parser() stores serde_json::Error; custom parsers can store any error type.

Fields

source: Box<dyn Error + Send + Sync>

Io

File I/O error.

Raised when a file exists but cannot be read (e.g. permission denied, is a directory).

Fields

path: PathBuf

source: Error

Trait Implementations

impl Debug for ResolveError

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

Formats the value using the given formatter.

impl Display for ResolveError

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

Formats the value using the given formatter.

impl Error for ResolveError

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.
