Typed error for mana-core’s public API surface.

Callers can match on variants to handle specific failure modes (e.g., distinguishing “unit not found” from “file corrupt”). Internal functions still use anyhow — this type lives at the API boundary.

Variants

UnitNotFound

The requested unit ID does not exist.

Fields

id: String

InvalidId

The unit ID is syntactically invalid (empty, special chars, path traversal).

Fields

id: String

reason: String

CycleDetected

Adding a dependency would create a cycle in the graph.

Fields

details: String

VerifyFailed

The verify command failed or timed out.

Fields

reason: String

ConfigError(String)

Problem reading or validating config.yaml.

IndexError(String)

Problem building, loading, or saving the index.

LockConflict(String)

Could not acquire the index lock (another process may hold it).

ParseError

YAML/frontmatter deserialization failed.

Fields

path: PathBuf

reason: String

IoError(Error)

Filesystem I/O failure.

Internal(Error)

Catch-all for internal errors that don’t fit a specific variant. Preserves the original anyhow::Error for debugging.

Trait Implementations

impl Debug for ManaError

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

Formats the value using the given formatter.

impl Display for ManaError

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

Formats the value using the given formatter.

impl Error for ManaError

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<Error> for ManaError

fn from(source: Error) -> ManaError

Converts to this type from the input type.

impl From<Error> for ManaError

fn from(source: Error) -> ManaError

Converts to this type from the input type.
