Enum CursorError 

#[non_exhaustive]
pub enum CursorError {
    InvalidBase64,
    InvalidFormat,
    TooLarge,
    TooManyFields,
}

Errors that can occur when parsing a cursor.

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.

InvalidBase64

The base64 encoding is invalid.

InvalidFormat

The cursor format is invalid.

TooLarge

The cursor exceeds the maximum allowed size.

TooManyFields

The cursor has too many fields.

Implementations

impl CursorError

pub const fn is_format_error(&self) -> bool

Returns true if this is an encoding/format error.

Includes InvalidBase64 and InvalidFormat.

pub const fn is_limit_error(&self) -> bool

Returns true if this is a size/limit error.

Includes TooLarge and TooManyFields.

Trait Implementations

impl Clone for CursorError

fn clone(&self) -> CursorError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CursorError

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

Formats the value using the given formatter.

impl Display for CursorError

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

Formats the value using the given formatter.

impl Error for CursorError

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 PartialEq for CursorError

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