Enum NodeError 

pub enum NodeError {
    Cbor(CborError),
    Shape {
        at: usize,
        why: String,
    },
    KeyNotUtf8 {
        at: usize,
    },
}

Why a block is not a Merkle search tree node.

Variants

Cbor(CborError)

The block is not DAG-CBOR at all.

Shape

The block decoded, and to something that is not a node.

Fields

at: usize

Which entry the problem is in, or 0 for the node itself.

why: String

What was wrong.

KeyNotUtf8

A key that is not UTF-8.

A repository path is a collection NSID and a record key, both of which are ASCII by rule. The tree is keyed on bytes and this crate is happy to compare bytes, but a path it cannot name is one it cannot report in a diff or an operation, so it is refused at the door rather than lost in the middle.

Fields

at: usize

Which entry the key is in.

Implementations

impl NodeError

fn shape(at: usize, why: impl Into<String>) -> Self

A shape error at one entry.

Trait Implementations

impl Clone for NodeError

fn clone(&self) -> NodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeError

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

Formats the value using the given formatter.

impl Display for NodeError

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

Formats the value using the given formatter.

impl Error for NodeError

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<CborError> for NodeError

fn from(source: CborError) -> Self

Converts to this type from the input type.

impl PartialEq for NodeError

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