Enum ic_types::hash_tree::LookupResult

pub enum LookupResult<'tree> {
    Absent,
    Unknown,
    Found(&'tree [u8]),
    Error,
}

A result of looking up for a certificate.

Variants

Absent

The value 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 this value.

Found(&'tree [u8])

The value was found at the referenced node.

Error

The path does not make sense for this certificate.

Trait Implementations

impl<'tree> Clone for LookupResult<'tree>

fn clone(&self) -> LookupResult<'tree>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tree> Debug for LookupResult<'tree>

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

Formats the value using the given formatter.

impl<'tree> PartialEq<LookupResult<'tree>> for LookupResult<'tree>

fn eq(&self, other: &LookupResult<'tree>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
