BridgeContext

Struct BridgeContext 

Source
pub struct BridgeContext { /* private fields */ }
Expand description

Context for rendering the runtime bridge template.

The forbidden-char/forbidden-env-name fields are rendered directly from mcp_execution_core’s canonical lists so the generated bridge’s copies structurally cannot drift from the Rust source of truth — see BridgeContext::default, the only way to construct one, which populates them from mcp_execution_core::forbidden_chars/ forbidden_env_names/forbidden_env_prefix rather than leaving them empty. This deliberately does not derive Default: an empty forbidden_chars would render a bridge whose validateCommandString accepts every shell metacharacter (fail-open on exactly the check this exists to enforce), so Default is hand-written to make “always populated” a property of the type rather than a convention callers must remember to uphold.

The three fields are private with read-only accessors for the same reason: pub fields would let BridgeContext { forbidden_chars: vec![], .. } bypass the invariant entirely and still compile, silently reintroducing the fail-open state Default exists to prevent. Deserialize is intentionally not derived — nothing in this codebase deserializes a BridgeContext from external input, and doing so would need to re-validate non-emptiness rather than trust the wire data.

§Examples

use mcp_execution_codegen::progressive::BridgeContext;

let context = BridgeContext::default();
assert!(!context.forbidden_chars().is_empty());
assert!(context.forbidden_chars().contains(&";".to_string()));
assert!(!context.forbidden_env_prefix().is_empty());

Implementations§

Source§

impl BridgeContext

Source

pub fn forbidden_chars(&self) -> &[String]

Shell metacharacters forbidden in a command or argument string, each pre-escaped for safe embedding inside a single-quoted TypeScript string literal. Never empty.

§Examples
use mcp_execution_codegen::progressive::BridgeContext;

assert!(!BridgeContext::default().forbidden_chars().is_empty());
Source

pub fn forbidden_env_names(&self) -> &[String]

Forbidden environment variable names (exact match). Never empty.

§Examples
use mcp_execution_codegen::progressive::BridgeContext;

assert!(!BridgeContext::default().forbidden_env_names().is_empty());
Source

pub fn forbidden_env_prefix(&self) -> &str

Environment-variable-name prefix rejected regardless of exact match (e.g. DYLD_). Never empty.

§Examples
use mcp_execution_codegen::progressive::BridgeContext;

assert!(!BridgeContext::default().forbidden_env_prefix().is_empty());

Source§

impl Default for BridgeContext

Source§

fn default() -> Self

Populates the forbidden-char/forbidden-env-name fields directly from mcp_execution_core’s canonical lists, so BridgeContext::default() can never render a bridge with an empty (fail-open) FORBIDDEN_CHARS. Each character is passed through sanitize_ts_string_literal (this crate’s TS-string-literal escaper) so it renders as a syntactically valid single-quoted TypeScript string literal regardless of what the Rust list contains.
