Struct sudoku_backend::ops::errors::GenericError

pub struct GenericError {
    pub reason: Cow<'static, str>,
    pub severity: GenericErrorSeverity,
}

Use this for most non-specific errors.

Refer to doc/errors.md for more details.

Examples

#[get("/endpoint")]
fn endpoint() -> Result<String, Json<GenericError>> {
    work().map_err(|e| Json(GenericError {
        reason: format!("couldn't finish work: {}", e).into(),
        severity: GenericErrorSeverity::Warning,
    }))
}

fn main() {
    rocket::ignite()
        .mount("/", routes![endpoint])
        .launch();
}

Fields

reason: Cow<'static, str>

In all-lowercase past-tense finishing-punctuation-free form.

For example: "failed to apply diff", "user with that name exists".

severity: GenericErrorSeverity

How bad the error is.

Trait Implementations

impl PartialEq<GenericError> for GenericError

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

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

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

This method tests for !=.

impl Clone for GenericError

fn clone(&self) -> GenericError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R: Into<Cow<'static, str>>> From<(R, GenericErrorSeverity)> for GenericError

fn from((r, s): (R, GenericErrorSeverity)) -> GenericError

Performs the conversion.

impl Ord for GenericError

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl Eq for GenericError

impl PartialOrd<GenericError> for GenericError

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

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

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

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

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

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

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

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

fn ge(&self, other: &GenericError) -> bool

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

impl Debug for GenericError

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

Formats the value using the given formatter.

impl Hash for GenericError

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 Serialize for GenericError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where     __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for GenericError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where     __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
