Struct KdlError 

pub struct KdlError {
    pub input: Arc<String>,
    pub diagnostics: Vec<KdlDiagnostic>,
}

The toplevel Error type for KDL: this is returned when a KDL document failed to parse entirely.

This diagnostic implements miette::Diagnostic and can be used to display detailed, pretty-printed diagnostic messages when using miette::Result and the "fancy" feature flag for miette:

fn main() -> miette::Result<()> {
    "foo 1.".parse::<kdl::KdlDocument>()?;
    Ok(())
}

This will display a message like:

Error:
  × Expected valid value.
   ╭────
 1 │ foo 1.
   ·     ─┬
   ·      ╰── invalid float
   ╰────
  help: Floating point numbers must be base 10, and have numbers after the decimal point.

Fields

input: Arc<String>

Original input that this failure came from.

diagnostics: Vec<KdlDiagnostic>

Sub-diagnostics for this failure.

Trait Implementations

impl Clone for KdlError

fn clone(&self) -> KdlError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KdlError

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

Formats the value using the given formatter.

impl Diagnostic for KdlError

fn source_code(&self) -> Option<&dyn SourceCode>

Source code to apply this Diagnostic’s Diagnostic::labels to.

fn related<'a>( &'a self, ) -> Option<Box<dyn Iterator<Item = &'a dyn Diagnostic> + 'a>>

Additional related Diagnostics.

fn code<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or enums will work just fine.

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by ReportHandlers to change the display format of this diagnostic.

fn help<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?

fn url<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

URL to visit for a more detailed explanation/help about this Diagnostic.

fn labels(&self) -> Option<Box<dyn Iterator<Item = LabeledSpan> + '_>>

Labels to apply to this Diagnostic’s Diagnostic::source_code

fn diagnostic_source(&self) -> Option<&dyn Diagnostic>

The cause of the error.

impl Display for KdlError

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

Formats the value using the given formatter.

impl Error for KdlError

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 From<KdlError> for KdlError

Available on crate feature v1 only.

fn from(value: KdlError) -> Self

Converts to this type from the input type.

impl PartialEq for KdlError

fn eq(&self, other: &KdlError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
