Enum luminance::tess::TessMapError

#[non_exhaustive]pub enum TessMapError {
    BufferMapError(BufferError),
    VertexTypeMismatch(VertexDesc, VertexDesc),
    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.

BufferMapError(BufferError)

The CPU mapping failed due to buffer errors.

VertexTypeMismatch(VertexDesc, VertexDesc)

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 buffer_map_error(e: BufferError) -> Self

The CPU mapping failed due to buffer errors.

pub fn vertex_type_mismatch(a: VertexDesc, b: VertexDesc) -> Self

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

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

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

pub fn forbidden_attributeless_mapping() -> Self

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

pub fn forbidden_deinterleaved_mapping() -> Self

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

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 Eq for TessMapError

impl Error for TessMapError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<BufferError> for TessMapError

fn from(e: BufferError) -> Self

Performs the conversion.

impl PartialEq<TessMapError> for TessMapError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
