What went wrong setting or parsing parameters.

Variants

Syntax

The text is not a parameter object.

Fields

at: usize

message: String

Unknown

The plugin has no parameter by that name.

Fields

key: String

known: Vec<String>

Type

The parameter exists but does not take a value of that kind.

Fields

key: String

wanted: &'static str

got: &'static str

Range

The value is outside what the parameter accepts.

Fields

key: String

value: f64

min: f64

max: f64

Unsupported

The plugin has parameters but this build cannot reach them.

Fields

message: String

Trait Implementations

impl Clone for ParamError

fn clone(&self) -> ParamError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamError

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

Formats the value using the given formatter.

impl Display for ParamError

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

Formats the value using the given formatter.

impl Error for ParamError

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 ParamError

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

Equality operator ==.

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

Inequality operator !=.
