Struct TooManyParameters 

#[non_exhaustive]
pub struct TooManyParameters;

Error raised when too many parameters are added to a ParametersBuilder.

Examples

use rune::TypeHash;
use rune::hash::ParametersBuilder;

let mut params = ParametersBuilder::new();

let err = 'outer: {
    for _ in 0.. {
        params = match params.add(i64::HASH) {
            Ok(params) => params,
            Err(err) => break 'outer err,
        };
    };

    panic!("expected error");
};

let err = err.to_string();

Trait Implementations

impl Debug for TooManyParameters

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

Formats the value using the given formatter.

impl Display for TooManyParameters

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

Formats the value using the given formatter.

impl Error for TooManyParameters

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>)
