Askama implements a template rendering engine based on Jinja. It generates Rust code from your templates at compile time based on a user-defined struct to hold the template's context. See below for an example, or read the book. "Pretty exciting. I would love to use this already." -- Armin Ronacher, creator of Jinja. All feedback welcome. Feel free to file bugs, requests for documentation and any other feedback to the issue tracker or tweet me. Askama was created by and is maintained by Dirkjan Ochtman.

QUESTION
I'm learning the rust language. So, I try to build a simple web app using sqlite3. But it gets multiple packages link error.
I saw some solution for this error(ex. this), but they didn't work.
The cause seems to be that the version specification of rusqlite
is wrong, but I don't know the correct version specification.
How should I configure the cargo.toml
?
Source codes are here.
cargo.toml
ANSWER
Answered 2021-Oct-01 at 10:46You're directly depending on rusqlite
and using r2d2-sqlite3
which itself depends on rusqlite
.
Since rusqlite
binds to a native library as the message indicates you can't have two versions of rusqlite linking to different versions of sqlite3(-sys), so you need to ensure you use the same version of rusqlite as r2d2.
If you're not going to publish on Cargo, the easiest by far is to leave rusqlite
's version as a wildcard ("*"
), that way the dependency resolver will give you whatever works for r2d2-sqlite3
. Otherwise you need to check the version of r2d2-sqlite3
you're using and match it.
Incidentally... r2d2-sqlite3 0.1.1? That seems to be over 4 years old, the current version seems to be 0.18. I'm slightly surprised r2d2 works, though I guess it changes relatively little (0.8.0 was 4 years ago, current is 0.8.9). Though I'm not sure what the utility of r2d2 is for sqlite3, especially for "a simple web app".
