Enum CapabilityTagError 

pub enum CapabilityTagError {
    Empty,
    ReservedPrefix {
        prefix: String,
        tag: String,
    },
}

Errors raised by tag construction / parsing.

Variants

Empty

Empty string passed to a parser. Distinct from “valid empty tag” because we don’t model emptiness as a tag.

ReservedPrefix

Application code tried to emit a tag with a reserved cross-axis prefix via Tag::parse_user. Substrate code that legitimately needs to emit such a tag uses Tag::parse instead.

Fields

prefix: String

The reserved prefix the offending tag started with.

tag: String

The full offending tag string, echoed back for diagnostics.

Trait Implementations

impl Clone for CapabilityTagError

fn clone(&self) -> CapabilityTagError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CapabilityTagError

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

Formats the value using the given formatter.

impl Display for CapabilityTagError

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

Formats the value using the given formatter.

impl Eq for CapabilityTagError

impl Error for CapabilityTagError

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<CapabilityTagError> for RequireParseError

fn from(source: CapabilityTagError) -> RequireParseError

Converts to this type from the input type.

impl PartialEq for CapabilityTagError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
