    MissingLeadingSlash(String),

The error returned when a path template is malformed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MissingLeadingSlash(String)

The template did not begin with /.

UnbalancedBraces(String)

A { was opened but never closed, or a } appeared unopened.

EmptyExpression(String)

A {} expression contained no name.

DuplicateVariable

The same variable name appeared more than once.

A template expression must not be repeated within one path.

Fields

template: String

The offending template.

name: String

The variable that appeared more than once.

NotAPath(String)

The template contained a query string or fragment.

IllegalLiteralCharacter

A literal segment contained a character the path grammar forbids.

Outside a {} expression a template may only carry pchar: letters, digits, -._~, the sub-delimiters !$&'()*+,;=, :, @, and percent-encoded triples. Anything else — including any non-ASCII character — has to arrive percent-encoded.

Fields

template: String

The offending template.

character: char

The character that is not allowed there.

MalformedPercentEncoding(String)

A % was not followed by two hexadecimal digits.

EmptySegment(String)

Two / met with nothing between them.

A path segment always holds at least one character. A trailing / is legal, because the grammar makes the final segment optional.

impl Eq for InvalidPathTemplate

impl Error for InvalidPathTemplate

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
