Enum PredicateWireError 

pub enum PredicateWireError {
    Empty,
    RootOutOfBounds {
        root_idx: u32,
        len: usize,
    },
    ChildOutOfBounds {

}

Errors raised by PredicateWire::into_predicate.

Variants

Empty

Wire payload had an empty nodes table.

RootOutOfBounds

root_idx was out of bounds for the nodes table.

Fields

root_idx: u32

The provided root_idx.

len: usize

Length of the nodes table.

ChildOutOfBounds

A composite node referenced a child index that was out of bounds.

Fields

child: u32

The malformed child index.

len: usize

Length of the nodes table.

CycleDetected

A composite node referenced a child index that was greater than or equal to its own. Catches index cycles introduced by malformed / malicious wire payloads.

Fields

parent: u32

Parent node index.

child: u32

Offending child index.

Trait Implementations

impl Clone for PredicateWireError

fn clone(&self) -> PredicateWireError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PredicateWireError

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

Formats the value using the given formatter.

impl Display for PredicateWireError

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

Formats the value using the given formatter.

impl Error for PredicateWireError

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<PredicateWireError> for PredicateRpcDecodeError

fn from(source: PredicateWireError) -> Self

Converts to this type from the input type.

impl PartialEq for PredicateWireError

fn eq(&self, other: &PredicateWireError) -> 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.
