Struct wat::Error

pub struct Error { /* fields omitted */ }

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.
