Folks, I’m getting stuck on a pretty simple issue using strum and serde crates is Rust.
First of all, I have this struct below:

use enums::Timezone;
use crate::CustomError;
use serde::{Deserialize, Serialize};
use serde_json::{from_str, to_string};

#[derive(Clone, Deserialize, Serialize, Debug, PartialEq)]
#[serde(rename_all = "snake_case")]
pub struct LocaleConfig {
    pub timezone: Timezone,
    pub language: String,
}
impl LocaleConfig {
    fn from_json_str(json_str: &str) -> Result<Self, CustomError> {
        from_str(json_str)?
    }

As you can see, I’m using a Timezone enum that follows:

use serde::{Deserialize, Serialize};
use strum_macros::{Display, EnumIter, EnumString};
#[derive(Clone, Copy, Deserialize, Serialize, Debug, PartialEq, EnumString, EnumIter, Display)]
pub enum Timezone {
    #[serde(rename = "GMT-12")]
    #[strum(serialize = "GMT-12")]
    UTCm12,
    #[serde(rename = "GMT-11")]
    #[strum(serialize = "GMT-11")]
    UTCm11,
...
    #[serde(rename = "GMT+11")]
    #[strum(serialize = "GMT+11")]
    UTCp11,
    #[serde(rename = "GMT+12")]
    #[strum(serialize = "GMT+12")]
    UTCp12,
}

The problem is that when I run LocaleConfig::from_json_str I get the following error:
Custom Error { title: "Serde Json Error", description: "unknown variant `timezone`, expected `Ok` or `Err` at line 1 column 11" }

As you can infer, CustomError is just a wrapper for my crates error. Also, please note that LocaleConfig and Timezone are located in different modules.

enums/Cargo.toml

[package]
name = "enums"

[dependencies]
serde = { workspace = true }
serde_json = { workspace = true }
strum = { version = "0.26.2" }
strum_macros = { version = "0.26.2" }

config/Cargo.toml

[package]
name = "config"
[dependencies]
serde = { workspace = true, features = ["derive"] }
serde_json = { workspace = true }
enums = { workspace = true }

And finally, my virtual manifest uses the versions that follow:

[workspace.dependencies.serde]
serde = { version = "1.0.197", features = ["derive"] }

[workspace.dependencies.serde_json]
version = "1.0.114"

What am I missing here? I mean, when I run: Timezone::from_str("GMT-5");, I get the correct enum, but I understand that the desererialize fn being run may differ.

Any insights on this matter?
