Rust SDK(bug): Missing Dependencies in Generated Cargo.toml Files

[iamnamananand996]

Description

The Rust SDK generator fails to include required dependencies (chrono, uuid, num-bigint) in generated Cargo.toml files when the API definitions use datetime, UUID, or big integer types.

Error Messages

error[E0432]: unresolved import `chrono`
error[E0433]: failed to resolve: use of unresolved module or unlinked crate `chrono`

Steps to Reproduce

1. Generate Rust SDK for an API that uses datetime types
2. Run cargo check on the generated SDK
3. Observe missing dependency errors

Affected Files

• seed/rust-sdk/unions/Cargo.toml
• seed/rust-sdk/exhaustive/Cargo.toml
• Multiple other generated SDKs

Expected Behavior

Generated Cargo.toml should automatically include:

[dependencies]
chrono = { version = "0.4", features = ["serde"] }
uuid = { version = "1.0", features = ["serde"] }
num-bigint = { version = "0.4", features = ["serde"] }

Root Cause

The type generator doesn't analyze API definitions to determine required dependencies before generating Cargo.toml files.
