Enum PrecompileWitnessError 

pub enum PrecompileWitnessError {
    TrueRoot,
    EmptyMerge,
    TooManyRoots {
        roots: usize,
        max: usize,
    },
    NonSingleton,
    Merge(PrecompileError),
    Integrity(IntegrityError),
}

Errors produced while constructing or merging precompile witnesses.

Variants

TrueRoot

A witness cannot represent an empty deferred execution.

EmptyMerge

A merge operation requires at least one singleton witness.

TooManyRoots

The ordered root sequence exceeds the hard allocation and folding safety ceiling.

Fields

roots: usize

max: usize

NonSingleton

Merge inputs must come directly from individual executions.

Merge(PrecompileError)

Sequential deferred-state aggregation failed.

Integrity(IntegrityError)

Deferred wire rehydration failed.

Trait Implementations

impl Debug for PrecompileWitnessError

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

Formats the value using the given formatter.

impl Display for PrecompileWitnessError

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

Formats the value using the given formatter.

impl Error for PrecompileWitnessError

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<IntegrityError> for PrecompileWitnessError

fn from(source: IntegrityError) -> Self

Converts to this type from the input type.
