Enum PrecompileError 

pub enum PrecompileError {
    MissingNode,
    InvalidNode,
    AssertionFailed,
    Other(DeferredError),
    Precompile {
        name: &'static str,
        source: Box<PrecompileError>,
    },
}

Errors produced while evaluating deferred nodes through precompiles.

Variants

MissingNode

A referenced child digest is not present in DeferredState.nodes.

InvalidNode

A tag is unknown or its payload shape is invalid for the decoded node type.

AssertionFailed

A precompile predicate evaluated to false.

Other(DeferredError)

A framework-level error surfaced by a precompile evaluation.

Precompile

Adds the owning precompile’s name to a tag or evaluation failure.

Registry construction errors are setup-time panics and are not represented here.

Fields

name: &'static str

source: Box<PrecompileError>

Implementations

impl PrecompileError

pub fn root(&self) -> &PrecompileError

Returns the underlying failure without registry attribution wrappers.

Trait Implementations

impl Clone for PrecompileError

fn clone(&self) -> PrecompileError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrecompileError

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

Formats the value using the given formatter.

impl Display for PrecompileError

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

Formats the value using the given formatter.

impl Error for PrecompileError

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<DeferredError> for PrecompileError

fn from(source: DeferredError) -> Self

Converts to this type from the input type.

impl From<PrecompileError> for IntegrityError

fn from(err: PrecompileError) -> Self

Converts to this type from the input type.
