Enum MeshError 

pub enum MeshError {
    Io(Error),
    InvalidKey(String),
    BadSignature,
    InvalidCertChain(String),
    CaveatAmplification,
    Expired(String),
    MalformedEnvelope(String),
    Replay,
    BadSequence {
        expected: u64,
        actual: u64,
    },
    Encoding(String),
}

Errors that can arise from agent-mesh primitives.

Variants

Io(Error)

Underlying I/O failure (file read/write, permission, etc.).

InvalidKey(String)

A key blob (private or public) was malformed or rejected by the underlying crypto library.

BadSignature

An ed25519 signature failed to verify against its claimed key and message.

InvalidCertChain(String)

A cert chain was structurally valid but semantically wrong — e.g. the user pubkey didn’t sign the embedded metadata.

CaveatAmplification

A delegated agent’s caveats are not ⊑ its parent’s — delegation is attenuation-only, so a child may never grant more authority than the parent it chains to.

Expired(String)

A credential or envelope was rejected because it claims an expired validity window.

MalformedEnvelope(String)

A wire envelope was structurally malformed (wrong shape, wrong CID, missing fields).

Replay

A duplicate nonce was observed (replay detection).

BadSequence

An envelope arrived with the wrong sequence number for its sender’s session.

Fields

expected: u64

actual: u64

Encoding(String)

A serialization/deserialization failure (hex, serde, etc.).

Trait Implementations

impl Debug for MeshError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MeshError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for MeshError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for MeshError

fn from(source: Error) -> Self

Converts to this type from the input type.
