Enum TreeError 

pub enum TreeError {
    NotPowerOfTwo(usize),
    TooHigh(usize),
    LeafIndexOutOfRange {
        index: usize,
        leaves: usize,
    },
}

Errors from constructing a Merkle tree over offer leaves.

Variants

NotPowerOfTwo(usize)

The leaf set is empty or not a power of two.

TooHigh(usize)

The tree is taller than MAX_TREE_HEIGHT, which HashLib.offerTreeTypeHash rejects on-chain with TreeTooHigh.

LeafIndexOutOfRange

The requested leaf is outside the tree’s leaf layer.

Fields

index: usize

leaves: usize

Trait Implementations

impl Clone for TreeError

fn clone(&self) -> TreeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TreeError

impl Debug for TreeError

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

Formats the value using the given formatter.

impl Display for TreeError

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

Formats the value using the given formatter.

impl Eq for TreeError

impl Error for TreeError

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<TreeError> for OfferTreeError

fn from(source: TreeError) -> Self

Converts to this type from the input type.

impl PartialEq for TreeError

fn eq(&self, other: &TreeError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
