Enum ProofError 

pub enum ProofError {
    Car(CarError),
    Roots(usize),
    NoCommit,
    Commit(CommitError),
    Tree(StoreError),
    Record(String),
}

Why a proof establishes nothing about a record.

Variants

Car(CarError)

The file is not a CAR file whose blocks hash to their names.

Roots(usize)

The file roots at something other than one commit.

NoCommit

The root’s block is not in the file.

Commit(CommitError)

The root is not a commit the repository signed with this key.

Tree(StoreError)

The walk from the tree root needs a block the file does not hold, or the tree is malformed.

Record(String)

The tree names a record, and the file does not hold it as one.

Trait Implementations

impl Clone for ProofError

fn clone(&self) -> ProofError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProofError

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

Formats the value using the given formatter.

impl Display for ProofError

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

Formats the value using the given formatter.

impl Error for ProofError

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<CarError> for ProofError

fn from(source: CarError) -> Self

Converts to this type from the input type.

impl From<CommitError> for ProofError

fn from(source: CommitError) -> Self

Converts to this type from the input type.

impl From<StoreError> for ProofError

fn from(source: StoreError) -> Self

Converts to this type from the input type.

impl PartialEq for ProofError

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