Enum OtsError 

pub enum OtsError {
    UnknownTag {
        observed: [u8; 8],
    },
    MalformedHeader {
        reason: String,
    },
    UnknownCommitmentOp {
        tag: u8,
    },
    EmptyProof,
    OtsCrateError(String),
}

Errors emitted by the OtsParser trait surface.

Errors are split by origin: parser-internal violations ([MalformedHeader], [UnknownCommitmentOp], [EmptyProof]) versus whitelist violations ([UnknownTag]) versus everything else that surfaced inside the opentimestamps crate ([OtsCrateError]). The split matters because [UnknownTag] is the hostile-upstream containment edge — the trait wrapper rejects it even when the upstream crate accepted the bytes.

Variants

UnknownTag

Tag stored in the attestation was not on the whitelist (Bitcoin / Pending only).

Fields

observed: [u8; 8]

Tag bytes as parsed from the file.

MalformedHeader

Magic, version, or digest-type framing did not parse as a valid DetachedTimestampFile.

Fields

reason: String

Human-readable parse failure detail.

UnknownCommitmentOp

A commitment-op tag inside the timestamp walk was not one of the upstream-recognized ops. Wrapped here so downstream surfaces see a stable type rather than the upstream Error variant.

Fields

tag: u8

Op tag byte the upstream parser flagged.

EmptyProof

Input bytes were empty. The wrapper rejects this before invoking the upstream parser so the error stays inside the trait surface rather than leaking through as an upstream Io error.

OtsCrateError(String)

Any other failure surfaced inside the opentimestamps crate. Wrapped with a stable String so a hostile upstream cannot expand the variant set on us.

Trait Implementations

impl Clone for OtsError

fn clone(&self) -> OtsError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OtsError

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

Formats the value using the given formatter.

impl Display for OtsError

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

Formats the value using the given formatter.

impl Error for OtsError

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 PartialEq for OtsError

fn eq(&self, other: &OtsError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
