Struct HiddenLineError 

#[non_exhaustive]
pub struct HiddenLineError {
    pub mesh: Option<MeshId>,
    pub error: GeomError,
}

A refused hidden-line request: the GeomError and, when one input mesh is at fault, which.

A consumer that drops elements one at a time reads mesh instead of parsing text. mesh is None for refusals of the whole request: limits, frame, near/far, crease threshold, region, an empty mesh list, memory, cancellation and a missing provider. The inner message does not repeat the mesh id; Display prefixes it.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

mesh: Option<MeshId>

The input mesh the refusal is about, if it is about one.

error: GeomError

Why the request was refused.

Implementations

impl HiddenLineError

pub const fn request(error: GeomError) -> Self

Refusal of the whole request.

pub const fn mesh(mesh: MeshId, error: GeomError) -> Self

Refusal caused by one input mesh.

Trait Implementations

impl Clone for HiddenLineError

fn clone(&self) -> HiddenLineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HiddenLineError

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

Formats the value using the given formatter.

impl Display for HiddenLineError

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

Formats the value using the given formatter.

impl Error for HiddenLineError

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 From<GeomError> for HiddenLineError

fn from(error: GeomError) -> Self

Converts to this type from the input type.

impl PartialEq for HiddenLineError

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

Equality operator ==.

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

Inequality operator !=.
