Enum MergeStateError 

pub enum MergeStateError {
    InvalidTransition {
        from: MergePhase,
        to: MergePhase,
    },
    NotFound(PathBuf),
    Serialize(String),
    Deserialize(String),
    Io(String),
}

Errors related to merge-state operations.

Variants

InvalidTransition

Invalid phase transition.

Fields

from: MergePhase

The current phase.

to: MergePhase

The attempted target phase.

NotFound(PathBuf)

The merge-state file was not found.

Serialize(String)

Serialization error.

Deserialize(String)

Deserialization error.

Io(String)

I/O error (not “not found”).

Trait Implementations

impl Clone for MergeStateError

fn clone(&self) -> MergeStateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MergeStateError

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

Formats the value using the given formatter.

impl Display for MergeStateError

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

Formats the value using the given formatter.

impl Error for MergeStateError

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<MergeStateError> for BuildPhaseError

fn from(e: MergeStateError) -> Self

Converts to this type from the input type.

impl From<MergeStateError> for PrepareError

fn from(e: MergeStateError) -> Self

Converts to this type from the input type.

impl From<MergeStateError> for ValidateError

fn from(e: MergeStateError) -> Self

Converts to this type from the input type.

impl PartialEq for MergeStateError

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