Enum matchit::InsertError

#[non_exhaustive]
pub enum InsertError {
    Conflict {
        with: String,
    },
    TooManyParams,
    UnnamedParam,
    InvalidCatchAll,
    MalformedPath,
}

Represents errors that can occur when inserting a new route.

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.

Conflict

The inserted path conflicts with an existing route.

This error may unexpectedly come up when registering routes like the following:

/user/:id
/user/get

This is due to the strict requirements of the internal radix tree, and should be fixed in the future.

Fields of Conflict

with: String

The existing route that the insertion is conflicting with.

TooManyParams

Only one parameter per path segment is allowed.

UnnamedParam

Parameters must be registered with a name.

InvalidCatchAll

Catch-all parameters are only allowed at the end of a path.

MalformedPath

Invalid tokens in the inserted path.

Trait Implementations

impl Clone for InsertError

fn clone(&self) -> InsertError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InsertError

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

Formats the value using the given formatter.

impl Display for InsertError

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

Formats the value using the given formatter.

impl Error for InsertError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl Hash for InsertError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for InsertError

fn cmp(&self, other: &InsertError) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<InsertError> for InsertError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<InsertError> for InsertError

fn partial_cmp(&self, other: &InsertError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

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