Enum ScoringPolicyError 

pub enum ScoringPolicyError {
    Parse(String),
    SchemaVersionMismatch {
        found: u32,
        expected: u32,
    },
    NonFiniteWeight {
        field: String,
        value: f64,
    },
}

All the ways scoring-policy parsing can fail.

Variants

Parse(String)

TOML body did not parse against the ScoringPolicy shape.

SchemaVersionMismatch

schema_version did not match SCHEMA_VERSION.

Fields

found: u32

The schema version we found.

expected: u32

The version we expected.

NonFiniteWeight

A numeric weight was non-finite or negative.

Fields

field: String

Dotted-path name of the offending field.

value: f64

The offending value.

Trait Implementations

impl Debug for ScoringPolicyError

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

Formats the value using the given formatter.

impl Display for ScoringPolicyError

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

Formats the value using the given formatter.

impl Error for ScoringPolicyError

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.
