Enum FitsError

    AmbiguousKeyword {
        keyword: String,

}

Errors from validated header mutations, ambiguous lookups, and oversized standalone serialization.

Parsing is lenient and does not produce these; header-only serialization (Header::to_header_bytes) is infallible.

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.

AmbiguousKeyword

A bare-name get/set/remove addressed a keyword that occurs more than once. Select one with an (name, occurrence) key.

Fields

keyword: String

The duplicated keyword.

count: usize

How many times it occurs.

KeywordTooLong

A keyword longer than the 8-character FITS field.

Fields

keyword: String

The offending keyword.

InvalidKeyword

A keyword containing bytes outside the FITS keyword set (A-Z 0-9 - _).

Fields

keyword: String

The offending keyword.

OccurrenceOutOfRange

An (name, occurrence) key targeted an occurrence that does not exist.

Fields

keyword: String

The keyword addressed.

occurrence: usize

The 0-based occurrence requested.

count: usize

How many occurrences exist.

DataTooLarge

Header::to_bytes declined to zero-fill a declared data segment larger than MAX_ZERO_FILL. Serialize the header with Header::to_header_bytes and supply the data yourself.

Fields

declared: u64

The data size the header declares (saturated on overflow).

max: u64

The cap it exceeds (MAX_ZERO_FILL).

Trait Implementations

impl Clone for FitsError

fn clone(&self) -> FitsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FitsError

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

Formats the value using the given formatter.

impl Display for FitsError

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

Formats the value using the given formatter.

impl Eq for FitsError

impl Error for FitsError

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 FitsError

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

Equality operator ==.

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

Inequality operator !=.
