Struct Res 

#[repr(C)]
pub struct Res {
    pub ulog2: i8,
    pub vlog2: i8,
}

Pixel resolution of a given texture. The resolution is stored in log form: ulog2 = log2(ures), vlog2 = log2(vres)). Note: negative ulog2 or vlog2 values are reserved for internal use.

Fields

ulog2: i8

log2 of u resolution, in texels

vlog2: i8

log2 of v resolution, in texels

Implementations

impl Res

pub fn val(&self) -> u16

impl Res

pub fn u(&self) -> i32

Return the log2 resolution in the u direction.

pub fn v(&self) -> i32

Return the log2 resolution in the v direction.

pub fn size(&self) -> i32

Return the size of the FaceInfo.

pub fn swapped_uv(&self) -> i32

Return a Res instance with swapped u, v values.

Trait Implementations

impl Clone for Res

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Res

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

Formats the value using the given formatter.

impl Default for Res

fn default() -> Self

Default constructor, sets res to 0 (1x1 texel).

impl ExternType for Res

type Kind = Trivial

Either cxx::kind::Opaque or cxx::kind::Trivial.

type Id

A type-level representation of the type’s C++ namespace and type name.

impl PartialEq for Res

fn eq(&self, res: &Res) -> 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.

impl Copy for Res

impl Eq for Res
