Enum CompositeKeyParseError 

#[non_exhaustive]
pub enum CompositeKeyParseError {
    MissingSeparator {
        separator: char,
    },
    InvalidFirst(KeyParseError),
    InvalidSecond(KeyParseError),
}

Error type for composite key parsing failures.

Returned by CompositeKey::from_str when the input string cannot be parsed as a valid CompositeKey.

Variants

• MissingSeparator — the separator character was not found.
• InvalidFirst — the first component failed validation.
• InvalidSecond — the second component failed validation.

Examples

use domain_key::{CompositeKey, CompositeKeyParseError};
use domain_key::{Domain, KeyDomain};

#[derive(Debug)]
struct UserDomain;
impl Domain for UserDomain { const DOMAIN_NAME: &'static str = "user"; }
impl KeyDomain for UserDomain {}

#[derive(Debug)]
struct PostDomain;
impl Domain for PostDomain { const DOMAIN_NAME: &'static str = "post"; }
impl KeyDomain for PostDomain {}

let err = "no-separator-here"
    .parse::<CompositeKey<UserDomain, PostDomain>>()
    .unwrap_err();
assert!(matches!(err, CompositeKeyParseError::MissingSeparator { separator: ':' }));

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.

MissingSeparator

The separator character was not found in the input string.

Fields

separator: char

The separator character that was expected but not found

InvalidFirst(KeyParseError)

The first component of the composite key failed to parse.

InvalidSecond(KeyParseError)

The second component of the composite key failed to parse.

Trait Implementations

impl Clone for CompositeKeyParseError

fn clone(&self) -> CompositeKeyParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompositeKeyParseError

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

Formats the value using the given formatter.

impl Display for CompositeKeyParseError

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

Formats the value using the given formatter.

impl Error for CompositeKeyParseError

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 IntoResponse for CompositeKeyParseError

fn into_response(self) -> Response

Create a response.

impl PartialEq for CompositeKeyParseError

fn eq(&self, other: &CompositeKeyParseError) -> 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.

impl ResponseError for CompositeKeyParseError

fn status_code(&self) -> StatusCode

Returns appropriate status code for error.

fn error_response(&self) -> HttpResponse

Creates full response for error.
