Enum QueryError 

pub enum QueryError {
    BearingProjectNotInWorkspace {
        name: String,
    },
    CanonicalisePattern {
        canonical: String,
    },
    GlobIntersect {
        source: GlobIntersectError,
    },
}

Failure produced by the query engine.

Maps to the EXEC-021 internal / configuration-error class per QRY-009. Each variant carries enough context to render a precise CLI diagnostic.

Variants

BearingProjectNotInWorkspace

The bearing project supplied by the caller does not exist in the workspace. Should not occur when the bearing project is derived from a cwd lookup via EXEC-022, but the engine surfaces it as a typed error rather than panicking.

Fields

name: String

The name of the missing project.

CanonicalisePattern

A canonicalised path pattern failed to re-parse after anchoring to its workspace-absolute form. Should not occur for patterns that already passed validation; the variant exists so the engine has a typed surface for any future canonicalisation regressions.

Fields

canonical: String

The offending canonicalised pattern string.

GlobIntersect

The glob-glob intersection routine failed for one of the --inputs / --outputs atoms.

Fields

source: GlobIntersectError

The underlying intersection-routine failure.

Trait Implementations

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

where Self: Debug + Display,

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 ErrorCompat for QueryError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
