Struct SamplerUse 

pub struct SamplerUse {
    pub address: [Address; 2],
    pub border: Option<[f32; 4]>,
    pub mip_lod_bias: Option<f32>,
    pub lod: Option<[f32; 2]>,
}

What a binding’s sampler gives a texture’s sampling: the addressing along u and v, the colour a border reads, and the level-of-detail bias and level range it states.

Fields

address: [Address; 2]

The addressing along u and v.

border: Option<[f32; 4]>

The colour a coordinate outside the texture reads along an Address::Border axis; finite, and stated where an axis is a border.

mip_lod_bias: Option<f32>

Added to a computed level of detail (Filtering::Trilinear); finite.

lod: Option<[f32; 2]>

The least and greatest level of detail the sampler reads: the level, its bias added, is clamped to them; finite and ordered.

Implementations

impl SamplerUse

pub fn addressed(address: [Address; 2]) -> SamplerUse

The addressing address, no border colour, no bias and no level range.

pub fn of( state: &SamplerState, unstated: Unstated, ) -> Result<SamplerUse, String>

From a binding’s sampler state: its u and v addressing (an unstated axis as unstated says), its border colour, its bias and its level range. Border addressing with no border colour is refused, as is a state that does not verify (SamplerState::verify: a colour, bias or range that isn’t finite, a reversed range). Whether an axis was assumed is SamplerUse::assumed.

pub fn assumed(state: &SamplerState) -> bool

Whether state leaves the u or v addressing unstated: what SamplerUse::of took from Unstated.
