Enum Error 

pub enum Error {
    NotAStore(NotAStore),
    Store(StoreError),
    Parse(ParseError),
    Policy {
        code: &'static str,
        message: String,
    },
    Io(Error),
}

Top-level error for dbmd-core operations.

Module-specific errors (ParseError, StoreError, NotAStore) convert into this so a CLI command can bubble a single error type while preserving the structured variant for --json rendering.

Variants

NotAStore(NotAStore)

The path is not a db.md store (no DB.md at the root). Surfaced as the machine-parseable code NOT_A_STORE with a non-zero exit.

Store(StoreError)

A store-level operation failed (walk, locate, shard, sidecar read).

Parse(ParseError)

A markdown / frontmatter / DB.md parse failed.

Policy

A write was refused by a DB.md ## Policies rule (e.g. a frozen page). Carries the structured validation code so the CLI can emit it verbatim.

Fields

code: &'static str

The structured issue code, e.g. "POLICY_FROZEN_PAGE".

message: String

Human-readable explanation.

Io(Error)

An underlying I/O failure.

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, __formatter: &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.

impl From<NotAStore> for Error

fn from(source: NotAStore) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(source: ParseError) -> Self

Converts to this type from the input type.

impl From<StoreError> for Error

fn from(source: StoreError) -> Self

Converts to this type from the input type.
