Struct ImageOptions 

#[non_exhaustive]
pub struct ImageOptions {
    pub cache_mode: ImageCacheMode,
    pub downscale: Option<ImageDownscaleMode>,
    pub mask: Option<ImageMaskMode>,
    pub entries: ImageEntriesMode,
}

Options for IMAGES.image.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

cache_mode: ImageCacheMode

If and how the image is cached.

downscale: Option<ImageDownscaleMode>

How the image is downscaled after decoding.

mask: Option<ImageMaskMode>

How to convert the decoded image to an alpha mask.

entries: ImageEntriesMode

How to decode containers with multiple images.

Implementations

impl ImageOptions

pub fn new( cache_mode: ImageCacheMode, downscale: Option<ImageDownscaleMode>, mask: Option<ImageMaskMode>, entries: ImageEntriesMode, ) -> Self

New.

pub fn cache() -> Self

New with only cache enabled.

pub fn none() -> Self

New with nothing enabled, no caching.

Trait Implementations

impl Clone for ImageOptions

fn clone(&self) -> ImageOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageOptions

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

Formats the value using the given formatter.

impl PartialEq for ImageOptions

fn eq(&self, other: &ImageOptions) -> 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.
