Enum SparseError 

pub enum SparseError {
    TooManyLeaves {
        actual: u64,
    },
    TooManyFilterPaths {
        actual: usize,
    },
    UnsortedTree,
}

Errors raised by build_sparse and verify_sparse. This is kept small — the transport layer will wrap these in its own error type once it lands.

Variants

TooManyLeaves

Source tree has more entries than MAX_LEAVES. The bitmap would still build, but we refuse out of caution: an attacker shouldn’t be able to force a multi-GB allocation on the verifier by claiming a huge leaf_count.

Fields

actual: u64

TooManyFilterPaths

Filter has more entries than MAX_FILTER_PATHS.

Fields

actual: usize

UnsortedTree

Source tree’s entries are not in strict lex order. Our leaf indices are defined by that order, so we refuse to build a manifest from a tree that violates the invariant.

Trait Implementations

impl Clone for SparseError

fn clone(&self) -> SparseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseError

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

Formats the value using the given formatter.

impl Display for SparseError

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

Formats the value using the given formatter.

impl Eq for SparseError

impl Error for SparseError

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 SparseError

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

Equality operator ==.

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

Inequality operator !=.
