i currently use Iosevka Nerd Font.
the cancel icon (X) looks too big and i want to change it to lowercase (x). i looked through the nvim-web-devicons readme and i also tried printing out all the available icons there
i.e. ```lua local devicons = require("nvim-web-devicons").get_icons() for _, value in pairs(devicons) do for i, v in pairs(value) do print(i .. "==>" .. v .. "\n") end end
``` but i couldnt find an icon with a name that matches X or cancel. what can i do to override this and replace with a custom one?
[edit] i use barbar.nvim for buffers btw.
i just tried akinsho/bufferline and the cancel icon looked normal. i suppose this is a barbar issue
[edit]:
okay turns out it was a barbar issue. just had to read through the README.md
properly haha.
``` M.config = function() require("barbar").setup({ icons = { button = "x", -- customize it to anything }, }) end
```
Hello, Thanks for responding. ^^
i didn't want to make any changes to the id field.
i have a user struct like this.
type User struct {
ID primitive.ObjectID `bson:"_id,omitempty" json:"id"`
FirstName string `bson:"firstname" json:"firstname"`
LastName string `bson:"lastname" json:"lastname"`
Email string `bson:"email" index:"email" json:"email"`
}
i wanted the Email field to be unique, just like the ID. so when a new user tries to create an account with the same email, it'll return an error.
it isn't a problem anymore because i figured out a way... i created a custom struct tag that validates whether a user with the same email exist in the database.

I'm trying to find a bson struct tag to create a unique index just like the one in the image attached to this post but for mongodb. i tried searching and i found nothing Close to what i need but this stackoverflow post https://stackoverflow.com/questions/30831316/how-to-specify-a-struct-with-a-multi-column-unique-index-for-gorm
