Enum RefineError 

#[non_exhaustive]
pub enum RefineError {
    RaggedIndices(usize),
    IndexOutOfRange(usize, u32),
    InvalidTarget(Scalar),
    SurfaceRefused(String),
    BudgetExceeded {
        produced: usize,
        limit: usize,

Why a refinement could not be performed.

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.

RaggedIndices(usize)

The index buffer is not a whole number of triangles.

IndexOutOfRange(usize, u32)

A triangle references a vertex that does not exist.

InvalidTarget(Scalar)

An edge-length target must be a positive, finite length.

SurfaceRefused(String)

A surface refused to place a projected vertex.

Propagated rather than absorbed. Falling back to the linear midpoint would return four times the triangles with none of the promised accuracy, and the caller could not tell the difference.

BudgetExceeded

Refinement would exceed the triangle budget.

Reported rather than silently truncated: a caller that asked for a 1mm edge on a building-sized model wants to know its request was impossible, not receive a partially refined mesh that looks fine.

Fields

produced: usize

Triangles the request would have produced.

limit: usize

The cap that was not raised.

Trait Implementations

impl Debug for RefineError

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

Formats the value using the given formatter.

impl Display for RefineError

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

Formats the value using the given formatter.

impl Error for RefineError

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 RefineError

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

Equality operator ==.

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

Inequality operator !=.
