Errors produced while validating or serializing an XMLDSig template.

Variants

InvalidNamespacePrefix(String)

A namespace prefix was not a supported XML NCName.

InvalidNamespaceUri(String)

A namespace URI could not be represented in an XML 1.0 declaration.

NamespacePrefixConflict(String)

An XPath binding would rebind the prefix used by XMLDSig elements.

InvalidId

An XMLDSig Id attribute was not a valid XML NCName.

Fields

element: &'static str

XMLDSig element carrying the Id attribute.

value: String

Rejected attribute value.

MissingReference

XMLDSig requires at least one reference in SignedInfo.

TooManyReferences

A template declared more references than signing and verification accept.

Fields

count: usize

Number of references supplied by the caller.

max: usize

Maximum references accepted for one signature.

TooManyTransforms

A reference exceeded the transform-chain limit shared with execution.

Fields

count: usize

Number of transforms supplied by the caller.

max: usize

Maximum transforms accepted by parsing and execution.

InvalidXPathFilterCount

XPath Filter 2.0 requires a non-empty, bounded expression sequence.

Fields

count: usize

Number of expressions supplied by the caller.

max: usize

Maximum expression count accepted by parsing and execution.

InvalidXPath(String)

An XPath parameter cannot be parsed or exceeds its resource bounds.

SigningAlgorithmDisabled(&'static str)

SHA-1 algorithms are available for verification but not new signatures.

Serialization(Error)

The XML writer failed.

InvalidUtf8(FromUtf8Error)

The writer unexpectedly emitted bytes that are not UTF-8.

Trait Implementations

impl Debug for SignatureBuilderError

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

Formats the value using the given formatter.

impl Display for SignatureBuilderError

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

Formats the value using the given formatter.

impl Error for SignatureBuilderError

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<Error> for SignatureBuilderError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for SignatureBuilderError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.

impl From<SignatureBuilderError> for SigningError

fn from(source: SignatureBuilderError) -> Self

Converts to this type from the input type.
