Implementations

impl HkError

pub fn render(&self, source: &str) -> String

Renders the error as a multi-line, rustc-style string: a boxed snippet of the surrounding source (when available) with a ^ caret under the exact column, plus a short “hint” for common mistakes. Returned as a String (rather than printed directly) so callers can log it, show it in a UI, write it to a file, or just print it — pretty_print below is a thin convenience wrapper around this that prints to stderr, kept for backwards compatibility with existing callers.

pub fn pretty_print(&self, source: &str)

Prints render(source) to stderr. Kept for backwards compatibility with existing callers (e.g. hpm’s own CLI) that expect this method to exist and print for them.

Trait Implementations

impl Debug for HkError

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

Formats the value using the given formatter.

impl Display for HkError

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

Formats the value using the given formatter.

impl Error for HkError

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<Error> for HkError

fn from(source: Error) -> Self

Converts to this type from the input type.
