Struct Redactor 

pub struct Redactor { /* private fields */ }

Output redactor that scrubs API keys, tokens, emails, and sensitive JSON keys from MCP tool output. Applies built-in patterns plus optional custom regexes.

Implementations

impl Redactor

pub fn try_new(custom_patterns: &[String]) -> Result<Self, Error>

Build a redactor with custom patterns.

Errors

Returns regex::Error if any custom pattern (or a built-in pattern) fails to compile.

pub fn new(custom_patterns: &[String]) -> Self

Build a redactor with custom patterns, logging a warning and skipping any invalid patterns.

If the built-in redaction patterns fail to compile (a bug), falls back to an empty set and logs an error rather than panicking.

pub fn redact(&self, input: &str) -> String

Scrub sensitive data from input using regex patterns and JSON-key matching.

Passes, in order: the value patterns (API keys, bearer tokens, JWTs, emails, … plus any custom patterns); credential parameters in URLs (?access_token=…, &sig=…); then keys. Key-based redaction applies to the whole output when it is JSON — including JSON carried inside its string values (IPC/network bodies are JSON-encoded strings) — and otherwise to "key": value pairs found in the text. Best effort: see the limits in docs/src/security.md.

Trait Implementations

impl Default for Redactor

fn default() -> Self

Returns the “default value” for a type.
