Enum Error

pub enum Error<V = StandardVertex>
where
    V: Debug,

    OutOfRange(V),
    NoNormal,
    DifferentLengthArrays,
    IrregularArray,

Errors occurred by polygon mesh handling

Variants

OutOfRange(V)

There is an index in out of range.

Examples

use truck_polymesh::*;
use errors::Error;

let positions = vec![
    Point3::new(0.0, 0.0, 0.0),
    Point3::new(1.0, 0.0, 0.0),
    Point3::new(0.0, 1.0, 0.0),
];
let faces = Faces::from_iter(&[
    &[0, 1, 2],
    &[1, 2, 4],
]);

let res = PolygonMesh::try_new(
    StandardAttributes {
        positions,
        ..Default::default()
    },
    faces,
);
match res {
    Err(Error::OutOfRange(vertex)) => {
        assert_eq!(vertex.pos, 4);
    }
    _ => panic!("wrong result!"),
}

NoNormal

There are no normal in polygon mesh.

DifferentLengthArrays

The length of arrays of StructuredMesh is incorrect.

IrregularArray

The length of arrays of StructuredMesh is incorrect.

Examples

use truck_polymesh::*;
use errors::Error;

let positions = vec![
    vec![Point3::new(0.0, 0.0, 0.0), Point3::new(1.0, 0.0, 0.0)],
    vec![Point3::new(0.0, 1.0, 0.0)],
];

match StructuredMesh::try_from_positions(positions) {
    Err(Error::IrregularArray) => {}
    _ => panic!("wrong result!"),
}

UnsortedDivision

The division of uv coords of StructuredMesh is not sorted.

Examples

use truck_polymesh::*;
use errors::Error;

let positions = vec![
    vec![Point3::new(0.0, 0.0, 0.0), Point3::new(0.0, 1.0, 0.0)],
    vec![Point3::new(1.0, 0.0, 0.0), Point3::new(1.0, 1.0, 0.0)],
];

let udiv = vec![1.0, 0.0];
let vdiv = vec![0.0, 1.0];

match StructuredMesh::try_from_positions_and_uvs(positions, (udiv, vdiv)) {
    Err(Error::UnsortedDivision) => {}
    _ => panic!("wrong result!"),
}

FromIO(Error)

Errors caused by obj files I/O.

Trait Implementations

impl<V> Debug for Error<V>

where V: Debug,

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

Formats the value using the given formatter.

impl<V> Display for Error<V>

where V: Debug,

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

Formats the value using the given formatter.

impl<V> Error for Error<V>

where V: Debug, Error<V>: Debug + Display,

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<V> From<Error> for Error<V>

where V: Debug,

fn from(source: Error) -> Error<V>

Converts to this type from the input type.

impl From<ParseFloatError> for Error

fn from(error: ParseFloatError) -> Error

Converts to this type from the input type.

impl From<ParseIntError> for Error

fn from(error: ParseIntError) -> Error

Converts to this type from the input type.
