Enum TileOutputPreference 

#[non_exhaustive]
pub enum TileOutputPreference {
    Cpu {
        backend: OutputBackendRequest,
    },

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.

Implementations

impl TileOutputPreference

pub fn cpu() -> Self

CPU-resident output; codec picks cheapest backend that returns host pixels.

pub fn cpu_only() -> Self

CPU-resident output with an explicit CPU backend request.

pub fn prefer_device_auto() -> Self

Prefer device output, fall back to CPU silently.

pub fn require_device_auto() -> Self

Require device output, letting the codec choose the device backend.

pub fn prefer_device_auto_with_compressed_decode() -> Self

Prefer device output and explicitly allow compressed source tile device decode.

pub fn require_device_auto_with_compressed_decode() -> Self

Require device output and explicitly allow compressed source tile device decode.

pub fn backend(&self) -> OutputBackendRequest

pub fn requires_device(&self) -> bool

pub fn prefers_device(&self) -> bool

pub fn compressed_device_decode_enabled(&self) -> bool

pub fn adaptive_decode_route_enabled(&self) -> bool

pub fn without_adaptive_decode_route(self) -> Self
