Defines AnimGifImage flags

Implementations

impl AnimGifImageFlags

pub const None: AnimGifImageFlags

No Event

pub const DONT_START: AnimGifImageFlags

This flag indicates to the loader that it should not start the animation immediately after successful load, which is the default. It can be started later using the \ref start() method.

pub const DONT_RESIZE_CANVAS: AnimGifImageFlags

This flag indicates to the loader that it should not resize the canvas widget of the animation to the dimensions of the animation, which is the default. Needed for special use cases.

pub const DONT_SET_AS_IMAGE: AnimGifImageFlags

This flag indicates to the loader that it should not set the animation as \ref image() member of the canvas widget, which is the default. Needed for special use cases.

pub const OPTIMIZE_MEMORY: AnimGifImageFlags

Often frames change just a small area of the animation canvas. This flag indicates to the loader to try using less memory by storing frame data not as canvas-sized images but use the sizes defined in the GIF file. The drawbacks are higher cpu usage during playback and maybe

pub const LOG_FLAG: AnimGifImageFlags

This flag can be used to print informations about the decoding process to the console.

pub const DEBUG_FLAG: AnimGifImageFlags

This flag can be used to print even more informations about the decoding process to the console.

impl AnimGifImageFlags

Get a flags value with all bits unset.

pub const fn all() -> AnimGifImageFlags

Get a flags value with all known bits set.

Convert from a bits value.

This method will return None if any unknown bits are set.

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<AnimGifImageFlags>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

pub fn remove(&mut self, other: AnimGifImageFlags)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: AnimGifImageFlags, value: bool)

Call insert when value is true or remove when value is false.

pub const fn difference(self, other: AnimGifImageFlags) -> AnimGifImageFlags

The intersection of a source flags value with the complement of a target flags value (&!).

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> AnimGifImageFlags

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl AnimGifImageFlags

pub const fn iter(&self) -> Iter<AnimGifImageFlags>

pub const fn iter_names(&self) -> IterNames<AnimGifImageFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
