Enum FetchError

#[non_exhaustive]
pub enum FetchError {
    CheckpointNotFound(RegistryLen),
    LogNotFound(LogId),
    FetchTokenNotFound(String),
    Message {
        status: u16,
        message: String,
    },
}

Represents a fetch API error.

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.

CheckpointNotFound(RegistryLen)

The provided checkpoint was not found.

LogNotFound(LogId)

The provided log was not found.

FetchTokenNotFound(String)

The provided fetch token was not found.

Message

An error with a message occurred.

Fields

status: u16

The HTTP status code.

message: String

The error message

Implementations

impl FetchError

pub fn status(&self) -> u16

Returns the HTTP status code of the error.

Trait Implementations

impl Debug for FetchError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FetchError

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FetchError

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

Formats the value using the given formatter.

impl Error for FetchError

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 Serialize for FetchError

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
