Module parser 

Cargo.toml parser with position tracking.

Parses Cargo.toml files using toml_edit to preserve formatting and extract precise LSP positions for every dependency field. Critical for features like hover, completion, and inlay hints.

Key Features

• Position-preserving parsing via toml_edit spans
• Handles all dependency formats: inline, table, workspace inheritance
• Extracts dependencies from all sections: dependencies, dev-dependencies, build-dependencies
• Converts byte offsets to LSP Position (line, UTF-16 character)

Examples

use deps_cargo::parse_cargo_toml;
use tower_lsp_server::ls_types::Uri;

let toml = r#"
[dependencies]
serde = "1.0"
"#;

let url = Uri::from_file_path("/test/Cargo.toml").unwrap();
let result = parse_cargo_toml(toml, &url).unwrap();
assert_eq!(result.dependencies.len(), 1);
assert_eq!(result.dependencies[0].name, "serde");
