Enum ReducerError 

pub enum ReducerError {
    MissingKind {
        raw: String,
    },
    UnknownKind {
        raw: String,
    },
    Comparison {
        raw: String,
        source: ComparisonError,
    },

        raw: String,
    },
    UnknownColumn {
        column: String,
        known: Vec<String>,
    },
}

A reducer that cannot be read or bound.

Variants

MissingKind

A reducer with no : between the column and the kind.

Fields

raw: String

Reducer as written.

UnknownKind

A kind no reducer has.

Fields

raw: String

Kind as written.

Comparison

A first kind whose comparison cannot be read.

Fields

raw: String

Kind as written, or as ReducerKind’s Display writes it.

source: ComparisonError

Reason the comparison is rejected.

BadWindow

A mean@ kind whose window is not START..END, with START at most END.

Fields

raw: String

Kind as written, or as ReducerKind’s Display writes it.

UnknownColumn

A column that no stat series produces.

Fields

column: String

Column as written in the reducer.

known: Vec<String>

Stat labels the model declares, or the column names once a build provides them.

Trait Implementations

impl Clone for ReducerError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReducerError

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

Formats the value using the given formatter.

impl Display for ReducerError

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

Formats the value using the given formatter.

impl Eq for ReducerError

impl Error for ReducerError

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 PartialEq for ReducerError

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

Equality operator ==.

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

Inequality operator !=.
