# Error::TypeTiny::WrongNumberOfParameters(3pm)

exception for Type::Params

## NAME

Error::TypeTiny::WrongNumberOfParameters - exception for Type::Params

## STATUS

This module is covered by the Type-Tiny stability policy.

## DESCRIPTION

Thrown when a Type::Params compiled check is called with the wrong number of parameters.

Also thrown by various parameterizable type constraints under similar circumstances. For example, the `"HashRef[Int]"` makes sense, but `"HashRef[Int, {}]"` does not.

This package inherits from Error::TypeTiny; see that for most documentation. Major differences are listed below:

### Attributes

- "minimum"

  The minimum expected number of parameters.

- "maximum"

  The maximum expected number of parameters.

- "got"

  The number of parameters actually passed to the compiled check.

- "target"

  A short string describing what there was the wrong number of parameters for.

### Methods

- "has\_minimum", "has\_maximum", "has\_target"

  Predicate methods.
