Struct SamplerState 

pub struct SamplerState {
    pub wrap: [Option<AddressMode>; 3],
    pub filters: Filters,
    pub max_anisotropy: Option<u8>,
    pub compare: Option<Compare>,
    pub mip_lod_bias: Option<f32>,
    pub border: Option<[f32; 4]>,
    pub lod: Option<[f32; 2]>,
}

A sampler’s state as the source stores it, for a texture slot or a program’s sampler: each part None where the source states none.

Fields

wrap: [Option<AddressMode>; 3]

Addressing along u, v and w.

filters: Filters

The sampler’s filters.

max_anisotropy: Option<u8>

The most texels along the axis of anisotropy an anisotropic filter takes (1: none beyond the filters’), where the source states an anisotropic filter.

compare: Option<Compare>

The comparison a depth-comparison sampler makes of the reference against the texel, where the sampler is one.

mip_lod_bias: Option<f32>

Added to the mip level the hardware computes, where the source states a non-zero bias.

border: Option<[f32; 4]>

The colour (red, green, blue, alpha) a coordinate outside the texture reads along an axis addressed AddressMode::Border, where the source states it.

lod: Option<[f32; 2]>

The least and the greatest mip level the sampler reads (the level of detail is clamped to them), where the source states a range; None is every level the texture has.

Implementations

impl SamplerState

pub fn verify(&self) -> Result<(), String>

The state agrees with itself: a stated border colour and level range are finite (the range’s top may be f32::MAX, every level), the range is not reversed, and a maximum anisotropy is at least 1.
