Struct ServerId 

pub struct ServerId(/* private fields */);

Server identifier (newtype over String).

Represents a unique identifier for an MCP server. Using a strong type prevents accidentally mixing server IDs with other string values, and ServerId::new enforces that every ServerId is safe to use as a single path segment (see validate_path_segment), since server IDs are ultimately confined into filesystem paths (e.g. ~/.claude/servers/{server_id}).

Examples

use mcp_execution_core::ServerId;

let id = ServerId::new("example-server").unwrap();
assert_eq!(id.as_str(), "example-server");
assert!(ServerId::new("../escape").is_err());

Deserialize is routed through ServerId::new (via #[serde(try_from = "String")]), so serde_json::from_str::<ServerId>(...) — or any struct with a ServerId field, such as mcp_execution_introspector::ServerInfo — enforces the same invariant as calling new directly; there is no separate, unvalidated deserialization path.

Implementations

impl ServerId

pub fn new(id: impl Into<String>) -> Result<Self, ServerIdError>

Creates a new server identifier, validating that id is a single non-empty path segment with no .. or path separator.

Errors

Returns ServerIdError::InvalidFormat if id is empty, or contains a .., a path separator, or a root/prefix component.

Examples

use mcp_execution_core::ServerId;

let id = ServerId::new("my-server").unwrap();
let from_string = ServerId::new(String::from("my-server")).unwrap();
assert_eq!(id, from_string);
assert!(ServerId::new("").is_err());
assert!(ServerId::new("a/b").is_err());

pub fn as_str(&self) -> &str

Returns the server ID as a string slice.

Examples

use mcp_execution_core::ServerId;

let id = ServerId::new("test").unwrap();
assert_eq!(id.as_str(), "test");

pub fn into_inner(self) -> String

Consumes the ServerId and returns the inner String.

Examples

use mcp_execution_core::ServerId;

let id = ServerId::new("test").unwrap();
let inner: String = id.into_inner();
assert_eq!(inner, "test");
