A query cannot produce either authoritative manual content or a quick reference.

Variants

EmptyName

A document selector was empty after trimming.

InvalidManualSection

A native manual category was empty or malformed.

InvalidSource

An explicit Markdown source name was empty.

ConflictingSourceSelectors

Markdown-source and native-manual selectors were combined.

EmptyMarkdownPath

A direct Markdown input path was empty.

UnsupportedInputFormat

Automatic format inference did not recognize a direct input.

Fields

path: String

Caller-facing input path.

EmptySelection

Excerpt projection was requested without selectors.

EmptySelector

An excerpt selector was empty.

EmptyEntry

An explanation entry name was empty.

InvalidSearch(SearchError)

Search configuration failed validation.

Markdown

Markdown input could not be read or parsed.

Fields

path: String

Caller-facing source path.

detail: String

Stable failure detail.

EmptyMarkdown

Markdown parsing produced neither document nor tldr content.

Fields

label: String

Selected-document label.

Registry

Registered-document discovery failed.

Fields

detail: String

Stable source-configuration or discovery detail.

Manual(ManualLoadError)

Native manual loading failed.

ManualWithTldr

No full document was found, but an optional tldr entry is available.

Fields

error: ManualLoadError

Native-manual failure retained as the authoritative lookup error.

topic: String

Topic that can be queried explicitly with --tldr.

TldrNotFound

An explicit tldr query found no quick-reference candidate.

Fields

topic: String

Requested tldr topic.

Tldr

An explicit tldr candidate could not be read or parsed.

Fields

topic: String

Requested tldr topic.

detail: String

Stable cache or Markdown failure detail.

NoReadableContent

No Markdown, manual, or quick-reference content could be resolved.

Fields

name: String

Requested document name.

Trait Implementations

impl Clone for QueryError

fn clone(&self) -> QueryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for QueryError

impl Error for QueryError

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 PartialEq for QueryError

fn eq(&self, other: &QueryError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
