feature version and crate version discrepancy

[leelhn2345]

Description

mismatch in the crate's version and the version shown in feature popup.

Neovim version

v0.11.3

Health check

Operating system and version

macOS 15.5

Expected behavior

require("crates").show_features_popup() should be of the same version as the crate's version.

in the latest version of the crate tauri-specta, require("crates").show_versions_popup() would show 1 more feature - derive.

Actual behavior

i have specified my crate's version to be of 2.0.0-rc.21.

but the features available are of an older version - 2.0.0-rc.9,
which is not the version that i specified.

not sure if it could be because the version is sorted in a lexicographical order.

Cargo.toml

[package]
name = "hello"
version = "0.1.0"
edition = "2024"

[dependencies]
tauri-specta = { version = "2.0.0-rc.21", features = ["typescript"] }

Steps to reproduce

1. nvim --clean -u minimal.lua
2. ...

Yes the version is matched because pre-release strings aren't correctly compared. See #139

[leelhn2345]

i opened a PR #169 to correctly compare the pre-release strings.

but the original bug stated in this issue still persists.

for example, i have specified an older pre-release version, but the features shown are that of the newest pre-release version.

the features shown should correspond to the specified version of the crate.

[saecki]

I agree this is a little bit confusing, but it's the way version matching is supposed to work.
If a blank version is specified, cargo interprets that as a caret ^ version requirement, which also matches versions upwards to some degree. The specifics are a little more complicated: https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#specifying-dependencies-from-cratesio

You can always pin a specific version using = (e.g. =2.0.0-rc.9)
(AFAIK that is recommended when using pre-releases where breakage can occur)

[leelhn2345]

ahh i see.

i have tested with =2.0.0-rc.9 and it does indeed only show the features of that version.

thank you so much for helping out. 😄
