# [NAME](#NAME)

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

# [STATUS](#STATUS)

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

# [DESCRIPTION](#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](#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](#Methods)

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

Predicate methods.
