Struct Error 

pub struct Error { /* private fields */ }

Errors from this crate related to parsing WAT files

An error can during example phases like:

• Lexing can fail if the document is syntactically invalid.
• A string may not be utf-8
• The syntactical structure of the wat file may be invalid
• The wat file may be semantically invalid such as having name resolution failures

Implementations

impl Error

pub fn set_path<P: AsRef<Path>>(&mut self, file: P)

To provide a more useful error this function can be used to set the file name that this error is associated with.

The file here will be stored in this error and later rendered in the Display implementation.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
