Error type for all error variants originated by this crate.

Variants

InvalidFormat

An invalid NIfTI-1 file was parsed. This is detected when reading the file's magic code, which should be either b"ni1\0" or b"n+1\0.

InconsistentDim(u8, u16)

The field dim is in an invalid state, as a consequence of dim[0] or one of the elements in 1..dim[0] + 1 not being positive.

OutOfBounds(Vec<u16>)

Attempted to read volume outside boundaries.

AxisOutOfBounds(u16)

Attempted to read a volume over a volume's unexistent dimension.

MissingVolumeFile(IOError)

Could not retrieve a volume file based on the given header file.

NoVolumeData

An attempt to read a complete NIFTI-1 object from a header file was made. It can also be triggered when a NIFTI object contains the magic code "ni-1\0", even if the following bytes contain the volume.

IncorrectVolumeDimensionality(u16, u16)

An incorrect number of dimensions was provided when interacting with a volume.

BadVolumeSize

Inconsistent or unsupported volume size (due to one or more dimensions being too large).

UnsupportedDataType(NiftiType)

This voxel data type is not supported. Sorry. :(

Io(IOError)

I/O Error

IncompatibleLength(usize, usize)

Raw data buffer length and volume dimensions are incompatible

IncorrectDescriptionLength(usize)

Description length must be lower than or equal to 80 bytes

InvalidCode(&'static str, i16)

Header contains a code which is not valid for the given attribute

Trait Implementations

impl Debug for NiftiError

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

Formats the value using the given formatter.

impl Display for NiftiError

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

Formats the value using the given formatter.

impl Error for NiftiError

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for NiftiError

pub fn from(err: IOError) -> NiftiError

Performs the conversion.
