Enum ParseError 

pub enum ParseError {
    Empty,
    InvalidIdentifier(String),
    InvalidFormat(String),
    SemanticKeyword(String),
    UnknownCrate {
        path: String,
        crate_name: String,
        known: String,
    },
}

SymbolPath parse error

Variants

Empty

The input string was empty (or contained only separators).

InvalidIdentifier(String)

A path segment was not a valid Rust identifier. Carries the offending segment.

InvalidFormat(String)

The overall path layout was malformed (e.g. leading/trailing ::, empty segment between ::). Carries the offending input.

SemanticKeyword(String)

A context-dependent keyword (crate, self, super) appeared in a path that requires canonical (absolute) form. Carries the offending keyword; the variant’s #[error] message walks the caller through how to resolve to a canonical name.

UnknownCrate

The leading crate segment did not match any registered crate. Carries the full path, the unrecognized crate segment, and a rendered list of known crate names for diagnostics.

Fields

path: String

Full SymbolPath input that triggered the error.

crate_name: String

The leading segment that did not match any known crate.

known: String

Comma-separated rendering of currently registered crate names.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<ParseError> for RegistrationError

fn from(source: ParseError) -> RegistrationError

Converts to this type from the input type.
