Struct Error

pub struct Error {
    pub spans: Vec<Range<usize>>,
    pub kind: Box<dyn ErrorKind>,
}

An error associated with regions of source code that can be highlighted.

Fields

spans: Vec<Range<usize>>

The regions of the source code that this error originated from.

kind: Box<dyn ErrorKind>

The kind of error that occurred.

Implementations

impl Error

pub fn new(spans: Vec<Range<usize>>, kind: impl ErrorKind + 'static) -> Self

Creates a new error with the given spans and kind.

pub fn build_report<'a>( &self, src_id: &'a str, ) -> Report<'_, (&'a str, Range<usize>)>

Build a report from this error kind.

pub fn report_to_stderr(&self, src_id: &str, input: &str) -> Result<()>

Writes the error to stderr.

The ariadne crate’s Report type does not have a Display implementation, so we can only use its eprint method to print to stderr.

pub fn report_to<W: Write>( &self, writer: W, src_id: &str, input: &str, ) -> Result<()>

Writes the error to an output stream.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.
