⚠ symposium-rust-analyzer breaking changes

--- failure function_requires_different_generic_type_params: function now requires a different number of generic type parameters ---

Description:
A function now requires a different number of generic type parameters than it used to. Uses of this function that supplied the previous number of generic types (e.g. via turbofish syntax) will be broken.
        ref: https://doc.rust-lang.org/reference/items/generics.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.47.0/src/lints/function_requires_different_generic_type_params.ron

Failed in:
  function build_server (0 -> 1 generic types) in /tmp/.tmppPkB8I/symposium-rust-analyzer/src/rust_analyzer_mcp.rs:192

--- failure struct_missing: pub struct removed or renamed ---

Description:
A publicly-visible struct cannot be imported by its prior path. A `pub use` may have been removed, or the struct itself may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.47.0/src/lints/struct_missing.ron

Failed in:
  struct symposium_rust_analyzer::RustAnalyzerProxy, previously in file /tmp/.tmpoIlr1B/symposium-rust-analyzer/src/lib.rs:14
