}

Errors that can potentially occur in wasm-pack.

Variants

Io(Error)

Maps any underlying I/O errors that are thrown to this variant

SerdeJson(Error)

A JSON serialization or deserialization error.

SerdeToml(Error)

A TOML serialization or deserialization error.

Cli

An error invoking another CLI tool.

Fields of Cli

message: String	Error message.
stderr: String	The underlying CLI's stderr output.

CrateConfig

A crate configuration error.

Fields of CrateConfig

message: String

A message describing the configuration error.

Methods

impl Error

pub fn cli(message: &str, stderr: Cow<str>) -> Result<(), Self>

Construct a CLI error.

pub fn crate_config(message: &str) -> Result<(), Self>

Construct a crate configuration error.

pub fn error_type(&self) -> String

Get a string description of this error's type.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Fail for Error

fn cause(&self) -> Option<&Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where     D: Display + Send + Sync + 'static,

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.

impl Display for Error

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

Formats the value using the given formatter.

impl From<Error> for Error

fn from(e: Error) -> Self

Performs the conversion.

impl From<Error> for Error

fn from(e: Error) -> Self

Performs the conversion.

impl From<Error> for Error

fn from(e: Error) -> Self

Performs the conversion.
