Enum CostError 

#[non_exhaustive]
pub enum CostError {
    WrongType {
        id: u64,
        actual: String,
        expected: &'static str,
    },
    MissingReference {
        from: u64,
        to: u64,
    },
}

Failures specific to interpreting cost data.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

WrongType

An entity was expected to be a cost entity but is not.

Fields

id: u64

The entity id.

actual: String

The type it actually has.

expected: &'static str

The type that was expected.

MissingReference

A referenced cost value or quantity does not exist.

Fields

from: u64

The referring cost item.

to: u64

The missing target.

Trait Implementations

impl Debug for CostError

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

Formats the value using the given formatter.

impl Display for CostError

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

Formats the value using the given formatter.

impl Error for CostError

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.
