Enum ApplyError 

pub enum ApplyError {
    UnknownNode {
        id: NodeId,
    },
    WrongNodeKind {
        id: NodeId,
        reason: String,
    },
    InvalidPayload {
        reason: String,
    },
}

Failure during Workspace::apply.

Why these particular variants

Every EditCommand variant targets a node by NodeId. The two failure modes are “that ID doesn’t exist” and “the ID exists but refers to a node of the wrong kind for this command”. Everything else (file-not-found when AddRuleSet with a missing path) is a validation issue reported via ApplyResult::diagnostics, not an error return.

Variants

UnknownNode

The NodeId in the command wasn’t found in the workspace.

Fields

id: NodeId

WrongNodeKind

The NodeId exists but names a node of the wrong kind for this command (e.g. DeleteRule pointing at a rule-set ID).

Fields

id: NodeId

reason: String

InvalidPayload

Invalid command payload (e.g. MoveRule with new_index past end of parent’s rule list).

Fields

reason: String

Trait Implementations

impl Debug for ApplyError

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

Formats the value using the given formatter.

impl Display for ApplyError

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

Formats the value using the given formatter.

impl Error for ApplyError

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.
