Struct Parameter

One parameter record of the container.

Fields

ty: u32

Original CGtype, CGresource and CGenum values, including unknown values.

resource: u32

The CGresource (a texture unit, an attribute, …).

variability: u32

The CGenum variability (varying, uniform, …).

resource_index: i32

The index within the resource, as a signed value.

name: Option<&'a [u8]>

NUL-terminated source strings, excluding their terminator; no encoding conversion.

semantic: Option<&'a [u8]>

The semantic string, where the parameter has one.

direction: u32

The CGenum direction (in, out, …).

parameter_number: i32

-1 denotes a global parameter.

referenced: bool

Whether the program references the parameter.

shared: bool

Whether the parameter is shared between programs.

default_value: Option<Vec<u32>>

The default value’s words as stored (big-endian, NaNs and signed zeros kept): one per component of the parameter’s numeric type (half, float, fixed, int and bool scalars, vectors and matrices; components). The container types the field CgBinaryFloatOffset, so the words are float bits whatever the type. A default on another type is refused.

embedded_constants: Vec<u32>

Byte offsets of 16-byte constants in this program’s microcode.

Implementations

impl Parameter<'_>

pub fn texture_unit(&self) -> Option<u32>

CG_TEXUNIT0 through CG_TEXUNIT15. A resource index alone is not a texunit.

Trait Implementations

impl<'a> Clone for Parameter<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Parameter<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for Parameter<'a>

impl<'a> PartialEq for Parameter<'a>

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

Equality operator ==.

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

Inequality operator !=.
