Enum PackError 

pub enum PackError {
    Loader {
        name: String,
        message: String,
    },
    Dsl(DslError),
    Cycle(String),
    DepthExceeded,
}

Side of an error: was it the parser, or did the loader callback fail?

Fields

name: String

Pack name as declared in metadata.extends.

Trait Implementations

impl Debug for PackError

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

Formats the value using the given formatter.

impl Display for PackError

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

Formats the value using the given formatter.

impl Error for PackError

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<DslError> for PackError

fn from(source: DslError) -> Self

Converts to this type from the input type.
