Enum SpeculativeOutputError 

#[non_exhaustive]
pub enum SpeculativeOutputError {
    Semantic {
        operation: String,
        message: String,
    },
    Publication {
        message: String,
    },
}

Structured failure in backend-independent speculative output handling.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Semantic

Transactional semantic parsing, decoding, or stop matching failed.

Fields

operation: String

Logical semantic operation.

message: String

Portable diagnostic detail.

Publication

A committed-token callback rejected publication.

Fields

message: String

Portable diagnostic detail.

Implementations

impl SpeculativeOutputError

pub fn semantic( operation: impl Into<String>, message: impl Into<String>, ) -> Self

Creates a semantic-state failure with operation context.

pub fn publication(message: impl Into<String>) -> Self

Creates a committed-output publication failure.

Trait Implementations

impl Clone for SpeculativeOutputError

fn clone(&self) -> SpeculativeOutputError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpeculativeOutputError

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

Formats the value using the given formatter.

impl Display for SpeculativeOutputError

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

Formats the value using the given formatter.

impl Eq for SpeculativeOutputError

impl Error for SpeculativeOutputError

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 SpeculativeOutputError

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

Equality operator ==.

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

Inequality operator !=.
