Enum TessMapError 

#[non_exhaustive]
pub enum TessMapError {
    CannotMap,
    VertexTypeMismatch(Vec<VertexBufferDesc>, Vec<VertexBufferDesc>),
    IndexTypeMismatch(TessIndexType, TessIndexType),
    ForbiddenAttributelessMapping,
    ForbiddenDeinterleavedMapping,
}

Error that can occur while trying to map GPU tessellations to host code.

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.

CannotMap

Cannot obtain a slice on the backend.

VertexTypeMismatch(Vec<VertexBufferDesc>, Vec<VertexBufferDesc>)

Vertex target type is not the same as the one stored in the buffer.

IndexTypeMismatch(TessIndexType, TessIndexType)

Index target type is not the same as the one stored in the buffer.

ForbiddenAttributelessMapping

The CPU mapping failed because you cannot map an attributeless tessellation since it doesn’t have any vertex attribute.

ForbiddenDeinterleavedMapping

The CPU mapping failed because currently, mapping deinterleaved buffers is not supported via a single slice.

Implementations

impl TessMapError

pub fn cannot_map() -> TessMapError

Cannot obtain a slice on the backend.

pub fn vertex_type_mismatch( a: Vec<VertexBufferDesc>, b: Vec<VertexBufferDesc>, ) -> TessMapError

Vertex target type is not the same as the one stored in the buffer.

pub fn index_type_mismatch(a: TessIndexType, b: TessIndexType) -> TessMapError

Index target type is not the same as the one stored in the buffer.

pub fn forbidden_attributeless_mapping() -> TessMapError

The CPU mapping failed because you cannot map an attributeless tessellation since it doesn’t have any vertex attribute.

pub fn forbidden_deinterleaved_mapping() -> TessMapError

The CPU mapping failed because currently, mapping deinterleaved buffers is not supported via a single slice.

Trait Implementations

impl Debug for TessMapError

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

Formats the value using the given formatter.

impl Display for TessMapError

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

Formats the value using the given formatter.

impl Error for TessMapError

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<SliceBufferError> for TessMapError

fn from(_: SliceBufferError) -> TessMapError

Converts to this type from the input type.

impl PartialEq for TessMapError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
