Function public_url 

pub fn public_url(ctx: &Ctx, key: &str) -> Result<String>

The permanent public URL of key in a public bucket: <STORAGE_PUBLIC_URL>/<key> (Active Storage’s public: true).

Requires public access on the bucket (an r2.dev URL, rate-limited and meant for development, or a custom domain) and the STORAGE_PUBLIC_URL variable. Every object of the bucket is then public forever to whoever has its key, with no authorization and no expiry: use it for avatars and product images, never for private documents. Pure string building: no R2 operation; downloads are class B operations on R2’s side.

Errors

Error::Internal (500) when STORAGE_PUBLIC_URL is not set (the message says how).

Examples

use ocre::{Ctx, Result, storage::{self, Attachment}};

fn avatar_src(ctx: &Ctx, avatar: &Attachment) -> Result<String> {
    storage::public_url(ctx, &avatar.key) // https://files.example.com/users/avatar/2u1Vd0zJ8sQqS6rJq0rVmA
