Enum Error 

pub enum Error {
    Sqlite(Error),
    Decode(Error),
    NameInUse(String),
    MissingNode(NodeHash),
    FormatMismatch {
        found: String,
        expected: u32,
    },
}

Errors the store can return.

Variants

Sqlite(Error)

Decode(Error)

NameInUse(String)

A ref with this name already exists; checkpoints are immutable and a branch may not clobber a checkpoint.

MissingNode(NodeHash)

A node referenced by hash is not present in the store.

FormatMismatch

The store on disk was written by a different AST format version. Pre-1.0 the node format is not stable; rather than silently mis-decode an incompatible store, opening it is refused.

Fields

found: String

expected: u32

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
