Module resolution error produced while loading imports.

Variants

Parse

Imported module failed to parse.

Fields

module: String

Logical module name requested by the importer.

source: String

Source file path where parsing failed.

error: SyntaxError

Underlying syntax error from parsing.

NotFound

Imported module path could not be resolved.

Fields

module: String

Logical module name requested by the importer.

from: String

Module containing the import statement.

path: String

Candidate filesystem path that was attempted.

source_name: String

Source file where the import appears.

span: SourceSpan

Span of the import clause.

ImportCycle

Cyclic import chain was detected.

Fields

cycle: String

Human-readable cycle path.

source_name: String

module: String

Module containing the duplicate import.

import: String

Duplicate imported module name.

source_name: String

Source file where the duplicate appears.

first_span: SourceSpan

Span of the first import declaration.

duplicate_span: SourceSpan

Span of the second import declaration.

BrowserStaticImportUnsupported

Browser import violated static-import restrictions.

Fields

allowed: String

Required static import path.

found: String

Import path found in source.

source_name: String

Source file containing the unsupported import.

span: SourceSpan

Implementations

impl ModuleError

pub fn diagnostic_line_column(&self) -> Option<(usize, usize)>

Return the primary diagnostic line/column when one is available.

Trait Implementations

impl Debug for ModuleError

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

Formats the value using the given formatter.

impl Display for ModuleError

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

Formats the value using the given formatter.

impl Error for ModuleError

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<DE> From<ModuleError> for CompileError<DE>

where DE: Error + 'static,

fn from(source: ModuleError) -> Self

Converts to this type from the input type.
