Enum QuorumTreeError 

pub enum QuorumTreeError {
    DuplicateChild {
        canonical_id: String,
    },
    UnsatisfiableQuorum {
        quorum_size: u64,
        num_children: usize,
    },
}

An error returned when building an invalid QuorumTree.

Both cases are caller bugs: a correct quorum rule never contains the same child twice and never requires more children than it has. Construction reports them instead of repairing the input, so the mistake surfaces where it is made.

Variants

DuplicateChild

The same child node was given more than once.

Fields

canonical_id: String

Canonical ID of the duplicated child node.

UnsatisfiableQuorum

quorum_size exceeds the number of child nodes, so no input could satisfy the tree.

Fields

quorum_size: u64

The required number of selected children.

num_children: usize

The number of child nodes.

Trait Implementations

impl Clone for QuorumTreeError

fn clone(&self) -> QuorumTreeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuorumTreeError

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

Formats the value using the given formatter.

impl Display for QuorumTreeError

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

Formats the value using the given formatter.

impl Eq for QuorumTreeError

impl Error for QuorumTreeError

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 QuorumTreeError

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