Enum SubtreeLookupResult

pub enum SubtreeLookupResult<Storage: AsRef<[u8]>> {
    Absent,
    Unknown,
    Found(HashTree<Storage>),
}

A result of looking up for a subtree.

Variants

Absent

The subtree at the provided path is guaranteed to be absent in the original state tree.

Unknown

This partial view does not include information about this path, and the original tree may or may note include a subtree at this path.

Found(HashTree<Storage>)

The subtree was found at the provided path.

Trait Implementations

impl<Storage: Clone + AsRef<[u8]>> Clone for SubtreeLookupResult<Storage>

fn clone(&self) -> SubtreeLookupResult<Storage>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Storage: Debug + AsRef<[u8]>> Debug for SubtreeLookupResult<Storage>

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

Formats the value using the given formatter.

impl<Storage: PartialEq + AsRef<[u8]>> PartialEq for SubtreeLookupResult<Storage>

fn eq(&self, other: &SubtreeLookupResult<Storage>) -> 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.
