Variants

Io(Error)

MalformedFaceGroup

One of the arguments to f is malformed.

Fields of MalformedFaceGroup

line_number: usizegroup: String

ArgumentListFailure

An argument list either has unparsable arguments or is missing one or more arguments.

Fields of ArgumentListFailure

line_number: usizelist: String

UnexpectedCommand

Command found that is not in the .obj spec.

Fields of UnexpectedCommand

line_number: usizecommand: String

MissingMTLName

mtllib command issued, but no name was specified.

Fields of MissingMTLName

line_number: usize

ZeroVertexNumber

Vertices are referenced using positive 1-based indices or negative relative indices.

Zero indices are invalid.

Trait Implementations

impl Debug for ObjError

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

Formats the value using the given formatter.

impl Display for ObjError

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

Formats the value using the given formatter.

impl Error for ObjError

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 ObjError

pub fn from(e: Error) -> Self

Performs the conversion.
