func Locals 

func Locals[V any](c Ctx, key any, value ...V) V

Locals function utilizing Go's generics feature. This function allows for manipulating and retrieving local values within a request context with a more specific data type.

All the values are removed from ctx after returning from the top RequestHandler. Additionally, Close method is called on each value implementing io.Closer before removing the value from ctx.

func Params 

func Params[V GenericType](c Ctx, key string, defaultValue ...V) V

Params is used to get the route parameters. This function is generic and can handle differnet route parameters type values.

Example:

http://example.com/user/:user -> http://example.com/user/john Params[string](c, "user") -> returns john

http://example.com/id/:id -> http://example.com/user/114 Params[int](c, "id") -> returns 114 as integer.

http://example.com/id/:number -> http://example.com/id/john Params[int](c, "number", 0) -> returns 0 because can't parse 'john' as integer.

func Query 

func Query[V GenericType](c Ctx, key string, defaultValue ...V) V

Query Retrieves the value of a query parameter from the request's URI. The function is generic and can handle query parameter values of different types. It takes the following parameters: - c: The context object representing the current request. - key: The name of the query parameter. - defaultValue: (Optional) The default value to return in case the query parameter is not found or cannot be parsed. The function performs the following steps:

  1. Type-asserts the context object to *DefaultCtx.
  2. Retrieves the raw query parameter value from the request's URI.
  3. Parses the raw value into the appropriate type based on the generic type parameter V. If parsing fails, the function checks if a default value is provided. If so, it returns the default value.
  4. Returns the parsed value.

If the generic type cannot be matched to a supported type, the function returns the default value (if provided) or the zero value of type V.

Example usage: 

GET /?search=john&age=8
name := Query[string](c, "search") // Returns "john"
age := Query[int](c, "age") // Returns 8
unknown := Query[string](c, "unknown", "default") // Returns "default" since the query parameter "unknown" is not found
