Struct rocket::http::uri::error::Error

pub struct Error<'a> { /* private fields */ }

Error emitted on URI parse failure.

Internally, the type includes information about where the parse error occurred (the error’s context) and information about what went wrong. Externally, this information can be retrieved (in textual form) through its Display implementation. In other words, by printing a value of this type.

Implementations

impl Error<'_>

pub fn index(&self) -> usize

Returns the byte index into the text where the error occurred if it is known.

Example

use rocket::http::uri::Origin;

let err = Origin::parse("/foo bar").unwrap_err();
assert_eq!(err.index(), 4);

Trait Implementations

impl<'a> Debug for Error<'a>

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

Formats the value using the given formatter.

impl Display for Error<'_>

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

Formats the value using the given formatter.

impl Error for Error<'_>

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 IntoOwned for Error<'_>

type Owned = Error<'static>

The owned version of the type.

fn into_owned(self) -> Error<'static>

Converts self into an owned version of itself.
