Struct DigestFormatError 

pub struct DigestFormatError { /* private fields */ }

Error returned when a candidate string is not a well-formed digest: exactly 64 lowercase ASCII hex characters (a hex-encoded SHA-256 digest).

Returned by both ConfigFingerprint and ToolDigest’s TryFrom<String> impl, which their #[serde(try_from = "String")] Deserialize routes every deserialization through — mirroring crate::ServerId/crate::ToolName’s validated-newtype pattern (see their own doc comments): no separate, unvalidated deserialization path exists for either type, so a hand-edited _meta.json cannot produce a value violating as_str’s documented “64-character lowercase-hex” contract.

Examples

use mcp_execution_core::provenance::{ConfigFingerprint, DigestFormatError};

let err = ConfigFingerprint::try_from("not-a-digest".to_string()).unwrap_err();
assert!(matches!(err, DigestFormatError { .. }));

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
