kandi X-RAY | rep Summary

rep is a Rust library. rep has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

rep is a tiny utility that lets you easily enforce representation/class invariants throughout your Rust data structures. Representation invariants are logical assertions that must hold true for every mutation of your data structure. For example, in your GIS application, you may have the following rep invariant for a LatLong. Enforcing representation invariants is easy with rep. Adding invariants to your data structures is just 2 easy steps.

Javascript is case sensitive. I see that you used subreport and it should be subReport with a capital R.

ANSWER

Answered 2021-Jun-15 at 13:26

While editing my initial question to add more context as Jay proposed I think it found the issue.

What probably happens? The view where the crash is, contains a table view. Each cell will be configured before being presented. I use a flag which holds the information, if the amount of weight for this cell (it is a strength workout app) has been initially set or is a change. When prepareForReuse is being called, this flag has not been reset. And that now means scrolling through the table view triggers a DB write for each reused cell, that leads to unnecessary writes to the db. Unnecessary, because the exact same number is already saved in the db.

My speculation: Scrolling fast could maybe lead to a race condition (I have read something about that issue with realm) and that maybe causes this weird crash, because there are multiple single writes initiated in a short time.

Solution: I now reset the flag on prepareForReuse to its initial value to prevent this misbehaviour.

The crash only happens when the cell is set up and the described behaviour happens. Therefor I'm quite confident I fixed the issue finally. Let's see. -- I was not able to reproduce the issue, but it also only happens pretty rare.

How do I make geom_bar colors change with gganimate when x and y are constant?

Asked 2021-Jun-15 at 01:12

I'm new to gganimate and was having difficulty figuring out how to do this.

I'd like to show the spread in two different levels of a variable by animating colour transitions. I want to show this by having the narrow level transition through a smaller range of colours than the wider level in the same amount of time. Is this possible?

Here's the reproducible example I have up-to now.

In R Shiny, why do my functions not work when using the render UI function but work fine when not using render UI?

Asked 2021-Jun-14 at 22:51

When running the first "almost MWE" code immediately below, which uses conditional panels and a "renderUI" function in the server section, it only runs correctly when I comment out the 3rd line from the bottom, observeEvent(vector.final(periods(),yield_input()),{yield_vector.R <<- unique(vector.final(periods(),yield_input()))}). If I run the code with this line activated, it crashes and I get the error message Error in [: subscript out of bounds which per my research means it is trying to access an array out of its boundary.

How to get biggest value from 2 or more fields in a subquery

Asked 2021-Jun-14 at 05:55

I have a table with customers that I join with a fact table with sales, based on invoices.

What I need from my report is to get in first part the biggest value of sales based on the incoming order type (1,2,3,C,D) for a customer for last year. And in the second part to get the same but for current year. What I get as result from my current query is all incoming order types with the customer revenue made for each of them. I tried with outer apply as subquery to get only the top 1 value ordered by revenue descending, but in the result I get the same - For all order types the customer revenue. Please help! I hope my explanation isn't understood only by me (happens a lot..)
