Invalid loading input or failure to acquire readable local content.

Variants

NativeBackendUnavailable

Native input was selected but this build does not enable the roff backend.

Fields

tldr_topic: Option<String>

Optional cached quick reference available through explicit tldr policy.

EmptyName

A document selector was empty after trimming.

InvalidManualSection

A native manual category was empty or malformed.

TldrManualSection

A tldr command query was qualified by a non-command manual section.

Fields

section: String

Incompatible native manual section.

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.

InvalidSelector

A document selector or source violated its bounded loading contract.

Fields

field: &'static str

Loading input field name.

error: ScopeTextError

Precise bound or character violation.

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 LoadError

fn clone(&self) -> LoadError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LoadError

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

Formats the value using the given formatter.

impl Display for LoadError

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

Formats the value using the given formatter.

impl Eq for LoadError

impl Error for LoadError

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 LoadError

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

Equality operator ==.

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

Inequality operator !=.
