Enum IdValidationError 

pub enum IdValidationError {
    InvalidFormat {
        kind: &'static str,
        value: String,
        expected: &'static str,
    },
    WrongPrefix {
        kind: &'static str,
        expected: &'static str,
    },
}

Error returned when a typed identifier fails parse-time validation.

Every RunId, NodeId, DiscussionId, and ProposalId is constructed only through its parse_str constructor (or the equivalent validating Deserialize), so any value that reaches a path helper has already been checked for prefix, charset, and length. This is the path-traversal guard: a raw id containing /, .., or a leading dot can never be turned into one of these newtypes, so it can never name a file outside the run directory.

Variants

InvalidFormat

The value carried the right prefix (or needs none) but its body had the wrong length or used characters outside the permitted charset.

Fields

kind: &'static str

Which id type rejected the value (run, node, discussion, spinoff).

value: String

The offending raw value.

expected: &'static str

Human-readable description of the accepted shape (e.g. n-NNNN).

WrongPrefix

The value did not start with the id type’s required prefix (n-, d-, s-).

Fields

kind: &'static str

Which id type rejected the value.

expected: &'static str

Human-readable description of the accepted shape.

Implementations

impl IdValidationError

pub fn kind(&self) -> &'static str

The id type that rejected the value (run, node, discussion, spinoff).

pub fn expected(&self) -> &'static str

The accepted-shape hint, suitable for the expected field of a CLI error envelope.

Trait Implementations

impl Clone for IdValidationError

fn clone(&self) -> IdValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdValidationError

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

Formats the value using the given formatter.

impl Display for IdValidationError

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

Formats the value using the given formatter.

impl Eq for IdValidationError

impl Error for IdValidationError

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 IdValidationError

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

Equality operator ==.

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

Inequality operator !=.
